Subject: ALSA: ice1712: Remove always NULL parameters
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=08a4c10b58d6403ca9fe8c872e22ecad47924fec;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: ice1712: Remove always NULL parameters

The various PCM allocation functions in this driver take a pointer to a
pointer of a PCM where if this parameter is provided the newly allocated PCM
is stored. All callers pass NULL though, so remove the parameter. This makes
the code a bit cleaner and shorter.
