[PATCH 01/13] net: ravb: Check return value of reset_control_deassert()

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

reset_control_deassert() could return an error. Some devices cannot work
if reset signal de-assert operation fails. To avoid this check the return
code of reset_control_deassert() in ravb_probe() and take proper action.

Fixes: 0d13a1a464a0 ("ravb: Add reset support")
