Subject: [PATCH 05/10] mfd: tps65010: Remove delcared and set, but never used variable 'status'

'status' hasn't been checked since 2008.

It's probably safe to remove it.

Fixes W=1 warning:

 drivers/mfd/tps65010.c:407:7: warning: variable ‘status’ set but not used [-Wunused-but-set-variable]
 407 | int status;
 | ^~~~~~
