Subject: [PATCH] block: use bdev_alignment_offset in
part_alignment_offset_show
Git-commit: 64dcc7c2717395b7c83ffb10f040d3be795d03c1
Patch-mainline: v5.19-rc1
References: jsc#PED-1183
Replace the open coded offset calculation with the proper helper.
This is an ABI change in that the -1 for a misaligned partition is
properly propagated, which can be considered a bug fix and matches
what is done on the whole device.
