Subject: block/md: fix md autodetection
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=55e8e30c382d25c34f8aafcc78efec948571a941;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Block ext devt conversion missed md_autodetect_dev() call in
rescan_partitions() leaving md autodetect unable to see partitions.
Fix it.
