Subject: [media] em28xx: fix uninitialized variable warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=430e35724bf008742a211d4c18a9b2dff1f61a86;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] em28xx: fix uninitialized variable warning

Fix this daily build warning:

In file included from build/media_build/v4l/em28xx-core.c:35:0:
build/media_build/v4l/em28xx-core.c: In function 'em28xx_audio_setup':
build/media_build/v4l/em28xx.h:798:2: warning: 'vid' may be used uninitialized in this function [-Wmaybe-uninitialized]
  printk(KERN_INFO "%s: "fmt,\
  ^
build/media_build/v4l/em28xx-core.c:507:6: note: 'vid' was declared here
  u32 vid;
      ^

As far as I can tell 'vid' can not really be used uninitialized here, but the code
is sufficiently complex that apparently gcc can't figure that out.
