From 4ac887cfdad909f16ee1886fe4fa19b452fc7fd3 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Tue, 6 Mar 2012 15:50:47 +0100 Subject: bcma: return error in bcma_sprom_get() when fallback fails When not SPROM is available a fallback mechanism is used. However, when that fails the code currently continues. This patch assures that the bcma_sprom_get() function aborts when that happens.
