Subject: [media] v4l2-flash-led-class: remove a now unused var
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bd676c0c04ec94bd830b9192e2c33f2c4532278d;p=linux-beck.git

[media] v4l2-flash-led-class: remove a now unused var

commit 079933dbcb02 ("[media] v4l: flash led class: Fix of_node release
in probe() error path") removed the need of an ancillary var at
the release function, as reported by smatch:

drivers/media/v4l2-core/v4l2-flash-led-class.c: In function 'v4l2_flash_release':
drivers/media/v4l2-core/v4l2-flash-led-class.c:678:23: warning: variable 'led_cdev' set but not used [-Wunused-but-set-variable]
  struct led_classdev *led_cdev;
                       ^~~~~~~~

Get rid of it.
