stable inclusion
from stable-v5.10.206
commit f230e6d4249b9ccdcb571077023cecabf91ecbb1
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8ZD3X
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.10.206&id=f230e6d4249b9ccdcb571077023cecabf91ecbb1

-------------------------

[ Upstream commit f0f214fe ]

Since scsi_get_lba() returns a sector_t value instead of the LBA, the name
of that function is confusing. Introduce an identical function
scsi_get_sector().
