Subject: [ALSA] sound: strlcpy is smart enough
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=023ff3eee6255390384e050d9daab1490c88edf8;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[ALSA] sound: strlcpy is smart enough

strlcpy already accounts for the trailing zero in its length
computation, so there is no need to substract one to the buffer size.
