Subject: [PATCH] zlib: move EXPORT_SYMBOL() and MODULE_LICENSE() out of dfltcc_syms.c
Date:   Fri, 18 Dec 2020 21:25:30 -0800

In 11fb479ff5d9 ("zlib: export S390 symbols for zlib modules"), I added
EXPORT_SYMBOL()s to dfltcc_inflate.c but then Mikhail said that these
should probably be in dfltcc_syms.c with the other EXPORT_SYMBOL()s.

However, that is contrary to the current kernel style, which places
EXPORT_SYMBOL() immediately after the function that it applies to,
so move all EXPORT_SYMBOL()s to their respective function locations
and drop the dfltcc_syms.c file. Also move MODULE_LICENSE() from the
deleted file to dfltcc.c.

Fixes: 11fb479ff5d9 ("zlib: export S390 symbols for zlib modules")
