[ Upstream commit3ba44ee966] When building the kernel with -Wmaybe-uninitialized, the compiler reports this warning: In function 'jffs2_mark_erased_block', inlined from 'jffs2_erase_pending_blocks' at fs/jffs2/erase.c:116:4: fs/jffs2/erase.c:474:9: warning: 'bad_offset' may be used uninitialized [-Wmaybe-uninitialized] 474 | jffs2_erase_failed(c, jeb, bad_offset); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ fs/jffs2/erase.c: In function 'jffs2_erase_pending_blocks': fs/jffs2/erase.c:402:18: note: 'bad_offset' was declared here 402 | uint32_t bad_offset; | ^~~~~~~~~~ When mtd->point() is used, jffs2_erase_pending_blocks can return -EIO without initializing bad_offset, which is later used at the filebad label in jffs2_mark_erased_block. Fix it by initializing this variable.
