Subject: ASoC: dmaengine: Replace strncpy() with strscpy_pad() for pcm->name
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=48118a9323ab715358bf63f5172c5c2b8cf5f455;p=linux.git

ASoC: dmaengine: Replace strncpy() with strscpy_pad() for pcm->name

While it is safe to use strncpy in this case, the advice is to move to
strscpy or strscpy_pad.
