[vlc-devel] [PATCH] Revert "android: util: remove redundant strncmp"

[Romain Vimont]

This reverts commit 77aa424b72d8b6a1e7049c430c90303b9473ed7d.

The replacement was not equivalent:

    strncmp(a, b, strlen(b)) == 0  # test if a starts with b
    strcmp(a, b) == 0              # test if a equals b

In practice, it breaks OpenGL on Android when the vout_modules contains
"gles2,none".
