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