Subject: Driver core: Don't remove kobjects in device_shutdown.
X-Git-Tag: firefly_0821_release~9833^2~3894^2~17
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=18ef545e47c126abd87c013b762b5fbb574858ce;p=firefly-linux-kernel-4.4.55.git

Driver core: Don't remove kobjects in device_shutdown.

device_shutdown is defined to just shutdown the hardware and to not
clean up any kernel data structures.  Therefore don't put the kobjects
for /sys/dev and /sys/dev/block and /sys/dev/char.

This ensures we don't remove /sys/dev/block and /sys/dev/char while
we still have symlinks from there to the actual devices.
