[vlc-devel] [PATCH] Fix two uninitialized variables in the v4l2 access module

[Alina Friedrichsen]

Without this patch, the initial value on my system is for example 3, so that two much items are counted. In the second step the function breaks with a error code, when the information downloading of the non-existing item fails.
