Subject: [PATCH v2] mtd: parsers: scpart: fix __udivdi3 undefined on mips
Date: Thu, 8 Dec 2022 23:28:29 +0300 [thread overview]
Message-ID: <805fe58e-690f-6a3f-5ebf-2f6f6e6e4599@gmail.com> (raw)
This fixes the following compile error on mips architecture with clang
version 16.0.0 reported by the 0-DAY CI Kernel Test Service:
ld.lld: error: undefined symbol: __udivdi3
referenced by scpart.c
mtd/parsers/scpart.o:(scpart_parse) in archive drivers/built-in.a
As a workaround this makes 'offs' a 32-bit type. This is enough, because
the mtd containing partition table practically does not exceed 1 MB. We
can revert this when the [Link] has been resolved.

Fixes: 9b78ef0c7997 ("mtd: parsers: add support for Sercomm partitions")
