Fabio M. De Francesco 912797e54c ALSA: pcm: Test for "silence" field in struct "pcm_format_data" ... commit 2f7a26abb8241a0208c68d22815aa247c5ddacab upstream. Syzbot reports "KASAN: null-ptr-deref Write in snd_pcm_format_set_silence".[1] It is due to missing validation of the "silence" field of struct "pcm_format_data" in "pcm_formats" array. Add a test for valid "pat" and, if it is not so, return -EINVAL.
