Subject: [PATCH] libata: stop setting sdev->host->max_sectors for lba48 drives
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f85bdb9ce9e130ce00f7a91523931fdd8f96f102;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] libata: stop setting sdev->host->max_sectors for lba48 drives

Avoid changing sdev->host->max_sectors because it can prevent use of
non-lba48 drives on other ports of the same adapter.
