Subject: ASoC: simple-card-utils: add __printf attribute
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e5668caec5698f14f310fb06bb39595b21d2fe4a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ASoC: simple-card-utils: add __printf attribute

asoc_simple_card_set_dailink_name() uses devm_kvasprintf() to format
some of its arguments.  Adding a __printf attribute to this function
makes it possible to detect at compile-time errors related to format
strings.
