Subject: [PATCH 3/4] mtd: ubi: Compile fastmap.c with -Wno-address-of-packed-member
Date: Sat, 7 Sep 2019 16:54:55 -0700 [thread overview]
Message-ID: <20190907235456.21535-3-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190907235456.21535-1-andrew.smirnov@gmail.com>
GCC9 for ARM produces the following warnings:
fastmap.c: In function 'ubi_attach_fastmap':
fastmap.c:700:31: warning: taking address of packed member of 'struct ubi_fm_scan_pool' may result in an unaligned pointer value [-Waddress-of-packed-member]
700 | ret = scan_pool(ubi, ai, fmpl->pebs, pool_size, &max_sqnum, &lfree);
| ~~~~^~~~~~
fastmap.c:704:34: warning: taking address of packed member of 'struct ubi_fm_scan_pool' may result in an unaligned pointer value [-Waddress-of-packed-member]
704 | ret = scan_pool(ubi, ai, fmpl_wl->pebs, wl_pool_size, &max_sqnum, &lfree);
| ~~~~~~~^~~~~~
the offending code seems OK and there doesn't seem to be a way to fix
this in code, so disable the warning for that file.
