| |
This patch fixes the following warning:
arch/arm/mm/alignment.c: In function 'do_alignment': arch/arm/mm/alignment.c:327:15: warning: 'offset.un' may be used uninitialized in this function [-Wmaybe-uninitialized] arch/arm/mm/alignment.c:749:21: note: 'offset.un' was declared here
The fix is to promote the initialization of offset into do_alignment().
