Subject: sound: allow the unit search until 256 in sound_core.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2abb80176cd80ad8e939ead9c785ac17dc9890a4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

sound: allow the unit search until 256 in sound_core.c

The upper limit of the available minors isn't necessarily 128 + unit,
but it's rather up to 256.  Fixing this allows more than 8 devices.
