However, we currently only set it for the Elantech touchpad later in psmattach(), thus `syncmask` is always configured. Now, we check `PSM_CONFIG_NOCHECKSYNC` and skip sync check if it is set. This fixes Elantech touchpad support for units which have `hascrc` set. To clarify that, when we log the `syncmask` and `syncbits` fields, also mention if they are actually used. Finally, when we set `PSM_CONFIG_NOCHECKSYNC`, clear `PSM_NEED_SYNCBITS` flag. PR: 225338 MFC of: r328190 |
