b43: Remove reset after fatal DMA error
As shown in Kernel Bugzilla #14761, doing a controller restart after a fatal DMA error does not accomplish anything other than consume the CPU on an affected system. Accordingly, substitute a meaningful message for the restart. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> [2.6.32] Signed-off-by: John W.
