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.
