Subject: skd: Convert explicit skd_request_fn() calls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8fe700650ef69a561a1745764aa42252cfee9c19;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

skd: Convert explicit skd_request_fn() calls

This will make it easier to convert this driver to the blk-mq
approach. This patch also reduces interrupt latency by moving
skd_request_fn() calls out of the skd_isr() interrupt.
