[PATCH 3.16 054/370] regmap: cache: Remove unused 'blksize' variable

[Ben Hutchings]

3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Kirtika Ruchandani <kirtika@xxxxxxxxxxxx>

commit daaadbf07433b15c452b2ff411a293b2ccd98e03 upstream.

Commit 2cbbb579bcbe ("regmap: Add the LZO cache support") introduced
'blksize' in  regcache_lzo_read() and regcache_lzo_write(), that is
set but not used. Compiling with W=1 gives the following warnings,
fix them.

drivers/base/regmap/regcache-lzo.c: In function âregcache_lzo_readâ:
drivers/base/regmap/regcache-lzo.c:239:9: warning: variable âblksizeâ set but not used [-Wunused-but-set-variable]
  size_t blksize, tmp_dst_len;
         ^
drivers/base/regmap/regcache-lzo.c: In function âregcache_lzo_writeâ:
drivers/base/regmap/regcache-lzo.c:278:9: warning: variable âblksizeâ set but not used [-Wunused-but-set-variable]
  size_t blksize, tmp_dst_len;
         ^

These are harmless warnings and are only being fixed to reduce the
noise with W=1 in the kernel.
