[alsa-devel] [PATCH v2 1/2] ASoC: simple-card-utils: add __printf attribute

[Nicolas Iooss]

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.
