[PATCH 1/2] staging: vt6656: Check the return values in vnt_set_bss_mode function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Check the return value of all the functions that return zero if
successful or a negative error code on failure inside the function
vnt_set_bss_mode.

Also, remove the unnecessary variable initialization as this variable is
set a few lines later.
