[PATCH net-next] drivers: net: wan: lmc: Fix W=1 set but used variable warnings

[Andrew Lunn]

drivers/net/wan/lmc/lmc_main.c: In function ‘lmc_ioctl’:
drivers/net/wan/lmc/lmc_main.c:356:25: warning: variable ‘mii’ set but not used 
[-Wunused-but-set-variable]

drivers/net/wan/lmc/lmc_main.c: In function ‘lmc_interrupt’:

used [-Wunused-but-set-variable]
 1188 |     u32 firstcsr;

This file has funky indentation, and makes little use of tabs. Keep
with this style in the patch, but that makes checkpatch unhappy.
