[PATCH 1/3] staging: wilc1000: Remove reference preceded by free

From: Punit Vara
Date: Sat Oct 24 2015 - 18:32:00 EST


This patch is to the wilc_wfi_cfgoperations.c file that fixes up
following error reported by coccicheck:

ERROR: reference preceded by free on line 1219

For (params->seq_len) <= 0 memory is already freed when
(params->seq_len) >0 then memory was alloted. So there is no need to use
kfree whenever params->seq_len <=0 remove it and place kfree inside
(params->seq_len) >0 condition.
