Subject: mtd: block2mtd: fix recursive call of mtd_writev
From: Gabor Juhos <juh...@openwrt.org>
commit 2e24e32e2759348c9290404abad4f729f791bfad upstream.
The 'mtd_writev' interface calls the function assigned
to the '_write' field of a given mtd device if that is
not NULL. The block2mtd driver sets the '_writev' field
to the 'mtd_writev' function itself and thus causes a
endless loop.
This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900
(mtd: harmonize mtd_writev usage).
Remove the assignment from the block2mtd driver to fix the
issue.
