drm/imagination: Fixed warning due to implicit cast to bool This line appears to confuse the compiler and had been noticed previously in clang-tidy output. There isn't anything fundamentally wrong that I can see. I suspect that it just looks like a mistake - hence the first note. By making the second operand an actual bool result, const correctness can be preserved while silencing the warning. >> drivers/gpu/drm/imagination/pvr_device_info.c:230:47: warning: use of logical '&&' with constant operand [-Wconstant-logical-operand] 230 | } else if (features_size == mapping_max_size && (mapping_max & 63)) { | ^ ~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/imagination/pvr_device_info.c:230:47: note: use '&' for a bitwise operation 230 | } else if (features_size == mapping_max_size && (mapping_max & 63)) { | ^~ | & drivers/gpu/drm/imagination/pvr_device_info.c:230:47: note: remove constant to silence this warning 230 | } else if (features_size == mapping_max_size && (mapping_max & 63)) { | ~^~~~~~~~~~~~~~~~~~~~~ 1 warning generated.

drm/imagination: Add GPU ID parsing and firmware loading Read the GPU ID register at probe time and select the correct features/quirks/enhancements. Use the GPU ID to form the firmware file name and load the firmware. The features/quirks/enhancements arrays are currently hardcoded in the driver for the supported GPUs. We are looking at moving this information to the firmware image. Changes since v8: - Corrected license identifiers Changes since v7: - Fix kerneldoc for pvr_device_info_set_enhancements() Changes since v5: - Add BRN 71242 to device info Changes since v4: - Retrieve device information from firmware header - Pull forward firmware header parsing from FW infrastructure patch - Use devm_add_action_or_reset to release firmware Changes since v3: - Use drm_dev_{enter,exit} Co-developed-by: Frank Binns <frank.binns@imgtec.com> Signed-off-by: Frank Binns <frank.binns@imgtec.com> Co-developed-by: Matt Coster <matt.coster@imgtec.com> Signed-off-by: Matt Coster <matt.coster@imgtec.com> Co-developed-by: Donald Robson <donald.robson@imgtec.com> Signed-off-by: Donald Robson <donald.robson@imgtec.com> Signed-off-by: Sarah Walker <sarah.walker@imgtec.com> Link: https://lore.kernel.org/r/1ff76f7a5b45c742279c78910f8491b8a5e7f6e6.1700668843.git.donald.robson@imgtec.com Signed-off-by: Maxime Ripard <mripard@kernel.org>
