mm: gup: remove set but unused local variable major
Patch series "Cleanups and fixup for gup".
This series contains cleanups to remove unneeded variable, useless BUG_ON
and use helper to improve readability. Also we fix a potential pgmap
refcnt leak. More details can be found in the respective changelogs.
This patch (of 5):
Since commit a2beb5f1ef
("mm: clean up the last pieces of page fault
accountings"), the local variable major is unused. Remove it.
