Subject: Replace for_each_*_bit_from() with for_each_*_bit() where appropriate
Git-commit: 749443de8dde3b8b420ee8b4daac4d929a6adeb9
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
A couple of kernel functions call for_each_*_bit_from() with start
bit equal to 0. Replace them with for_each_*_bit().
No functional changes, but might improve on readability.
