ABI: sysfs-driver-ufs: Add another What for platform drivers
The current what expressions: What: /sys/bus/platform/drivers/ufshcd/*/... Doesn't actually match what (some?) platform drivers actually export. For instance, drivers/scsi/ufs/ufs-hisi.c actually creates the sysfs struct for ufshcd inside this directory: /sys/devices/platform/soc/ff3c0000.ufs Which has those aliases: /sys/devices/virtual/devlink/platform:fff35000.crg_ctrl--platform:ff3c0000.ufs/consumer/ /sys/bus/platform/drivers/ufshcd-hisi/ff3c0000.ufs/ /sys/bus/platform/devices/soc/ff3c0000.ufs/ /sys/bus/platform/devices/ff3c0000.ufs/ So, add another What: for such files that will match the device ufs entries, e. g.: What: /sys/bus/platform/devices/*.ufs/ Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/bc61469964bbcabe38d12aa88f2734d38a8741e5.1632750608.git.mchehab+huawei@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
