Subject: [patch 01/12] zlib: export S390 symbols for zlib modules
Date: Sat, 05 Dec 2020 22:14:38 -0800 [thread overview]
Message-ID: <20201206061438.EIlu-Bvu8%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201205221412.67f14b9b3a5ef531c76dd452@linux-foundation.org>

Subject: zlib: export S390 symbols for zlib modules
Fix build errors when ZLIB_INFLATE=m and ZLIB_DEFLATE=m and ZLIB_DFLTCC=y
by exporting the 2 needed symbols in dfltcc_inflate.c.
Fixes these build errors:
ERROR: modpost: "dfltcc_inflate" [lib/zlib_inflate/zlib_inflate.ko] undefined!
ERROR: modpost: "dfltcc_can_inflate" [lib/zlib_inflate/zlib_inflate.ko] undefined!
Link: https://lkml.kernel.org/r/20201123191712.4882-1-rdunlap@infradead.org
Fixes: 126196100063 ("lib/zlib: add s390 hardware support for kernel zlib_inflate")
