ALSA: hwdep: Move put_user() call out of scoped_guard() in snd_hwdep_control_ioctl() Clang prior to 17.0.0 has a bug in its asm goto jump scope analysis to determine that no variables with the cleanup attribute are skipped by an indirect jump. Instead of only checking the scope of each label that is a possible target of each asm goto statement, it checks the scope of every label, which can cause an error when a variable with the cleanup attribute is used between two asm goto statements with different scopes, even if they have completely different label targets: sound/core/hwdep.c:273:8: error: cannot jump from this asm goto statement to one of its possible targets if (get_user(device, (int __user *)arg)) ^ arch/powerpc/include/asm/uaccess.h:295:5: note: expanded from macro 'get_user' __get_user(x, _gu_addr) : \ ^ arch/powerpc/include/asm/uaccess.h:283:2: note: expanded from macro '__get_user' __get_user_size_allowed(__gu_val, __gu_addr, __gu_size, __gu_err); \ ^ arch/powerpc/include/asm/uaccess.h:199:3: note: expanded from macro '__get_user_size_allowed' __get_user_size_goto(x, ptr, size, __gus_failed); \ ^ arch/powerpc/include/asm/uaccess.h:187:10: note: expanded from macro '__get_user_size_goto' case 1: __get_user_asm_goto(x, (u8 __user *)ptr, label, "lbz"); break; \ ^ arch/powerpc/include/asm/uaccess.h:158:2: note: expanded from macro '__get_user_asm_goto' asm_volatile_goto( \ ^ include/linux/compiler_types.h:366:33: note: expanded from macro 'asm_volatile_goto' #define asm_volatile_goto(x...) asm goto(x) ^ sound/core/hwdep.c:291:9: note: possible target of asm goto statement if (put_user(device, (int __user *)arg)) ^ arch/powerpc/include/asm/uaccess.h:66:5: note: expanded from macro 'put_user' __put_user(x, _pu_addr) : -EFAULT; \ ^ arch/powerpc/include/asm/uaccess.h:52:9: note: expanded from macro '__put_user' \ ^ sound/core/hwdep.c:276:4: note: jump bypasses initialization of variable with __attribute__((cleanup)) scoped_guard(mutex, ®ister_mutex) { ^ include/linux/cleanup.h:169:20: note: expanded from macro 'scoped_guard' for (CLASS(_name, scope)(args), \ To avoid this issue, move the put_user() call out of the scoped_guard() scope, which allows the asm goto scope analysis to see that the variable with the cleanup attribute will never be skipped by the asm goto statements. There should be no functional change because prior to the refactoring, put_user() was not called under register_mutex, so this call does not even need to be in the scoped_guard() in the first place.

ALSA: hwdep: Use guard() for locking We can simplify the code gracefully with new guard() macro and co for automatic cleanup of locks. There are still a few remaining explicit mutex_lock/unlock calls, and those are for the places where we do temporary unlock/relock, which doesn't fit well with the guard(), so far.

sched/wait: Rename wait_queue_t => wait_queue_entry_t Rename: wait_queue_t => wait_queue_entry_t 'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue", but in reality it's a queue *entry*. The 'real' queue is the wait queue head, which had to carry the name. Start sorting this out by renaming it to 'wait_queue_entry_t'. This also allows the real structure name 'struct __wait_queue' to lose its double underscore and become 'struct wait_queue_entry', which is the more canonical nomenclature for such data types.

ALSA: hwdep: Embed struct device Like the previous patch, this one embeds the device object into hwdep object. For a proper object lifecycle, it's freed in the release callback. This also allows us to create sysfs entries via passing to the groups field of the device without explicit function calls. Since each driver can see the device and touch its groups field directly, we don't need to delegate in hwdep core any longer. So, remove the groups field from snd_hwdep, and let the user (in this case only hda_hwdep.c) modify the device groups.

[ALSA] dynamic minors (3/6): store device-specific object pointers dynamically Instead of storing the pointers to the device-specific structures in an array, put them into the struct snd_minor, and look them up dynamically. This makes the device type modules independent of the minor number encoding. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

[ALSA] dynamic minors (1/6): store device type in struct snd_minor Instead of a comment string, store the device type in the snd_minor structure. This makes snd_minor more flexible, and has the nice side effect that we don't need anymore to create a separate snd_minor template for registering a device but can pass the file_operations directly to snd_register_device().

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
