Subject: drivers/block/loop.c: emit uevent on auto release
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8a9c594422ecad912d6470888acdee9a1236ad68;p=linux-beck.git

drivers/block/loop.c: emit uevent on auto release

The loopback driver failed to emit the change uevent when auto releasing
the device.  Fixed lo_release() to pass the bdev to loop_clr_fd() so it
can emit the event.
