Subject: ASoC: core: set_tdm_slot() will return -ENOTSUPP if no operation provided
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b2cbb6e1c1544fc889ee7d6c6a6c229c20cd03cd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ASoC: core: set_tdm_slot() will return -ENOTSUPP if no operation provided

Make it easier for generic code to work with set_tdm_slot() by distinguishing
between the operation not being supported and an error as is done.
