Subject: ide-cris: fix ->speedproc and wrong ->swdma_mask
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=55e4dee32916a569112f33a511adab4bd72cc4a2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ide-cris: fix ->speedproc and wrong ->swdma_mask

* fix ->speedproc to set the drive speed

* this driver doesn't support SWDMA so use the correct ->swdma_mask

* BUG() if an unsupported mode is passed to ->speedproc
