Kemeng ShiandGreg Kroah-Hartman fda080767c sbitmap: remove unnecessary calculation of alloc_hint in __sbitmap_get_shallow 
[ Upstream commit f1591a8bb3 ]

Updates to alloc_hint in the loop in __sbitmap_get_shallow() are mostly
pointless and equivalent to setting alloc_hint to zero (because
SB_NR_TO_BIT() considers only low sb->shift bits from alloc_hint). So
simplify the logic.
