From c5b057b55fb9822544995f9268de871ebac81f12 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Wed, 10 Oct 2012 11:13:11 -0700 Subject: brcmfmac: remove 'always false' condition from brcmf_c_mkiovar_bsscfg The parameter buflen is unsigned so the condition buflen < 0 is always false. The patch fixes the if statement checking the buffer length.
