From e01b16a7e217a23eb97e08d0a591735d5aee5efc Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Fri, 2 Dec 2016 15:51:33 +0000 Subject: sfc: remove EFX_BUG_ON_PARANOID, use EFX_WARN_ON_[ONCE_]PARANOID instead Logically, EFX_BUG_ON_PARANOID can never be correct. For, BUG_ON should only be used if it is not possible to continue without potential harm; and since the non-DEBUG driver will continue regardless (as the BUG_ON is compiled out), clearly the BUG_ON cannot be needed in the DEBUG driver. So, replace every EFX_BUG_ON_PARANOID with either an EFX_WARN_ON_PARANOID or the newly defined EFX_WARN_ON_ONCE_PARANOID. Signed-off-by: Edward Cree Signed-off-by: David S.
