Subject: ide: add IDE_HFLAG_NO_ATAPI_DMA host flag
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=33c1002ed912ac9dacedd5d5b166da3b72d18460;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git
ide: add IDE_HFLAG_NO_ATAPI_DMA host flag
Add IDE_HFLAG_NO_ATAPI_DMA host flag and set it in host drivers which
don't support ATAPI DMA. Then remove no longer needed hwif->atapi_dma.
