Subject: ASoC: rt5663: add in missing loop counter to avoid infinite loop
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=09b8852c759917e3ea10062b374692a5313cbfd8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ASoC: rt5663: add in missing loop counter to avoid infinite loop

The loop counter 'count' is missing an increment, so we could end up
with an infinite loop.  Add in a pre-increment to count to fix this.
