[PATCH] mtd: ubi: remove __exit annotation on ubiblock_exit

From: Arnd Bergmann
Date: Fri Jul 19 2024 - 03:39:30 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

Calling an __exit function from an __init function leads to undefined behavior
when the drier is built-in and the __exit functions are dropped from the
object:

WARNING: modpost: drivers/mtd/ubi/ubi: section mismatch in reference: ubi_init+0xbe (section: .init.text) -> ubiblock_exit (section: .exit.text)
ERROR: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.

Remove the now incorrect annotation.

Fixes: 72f3d3daddd7 ("mtd: ubi: Restore missing cleanup on ubi_init() failure path")
