Subject: [PATCH v4 1/6] scsi: ufs: Remove stringize operator '#' restriction
Date: Tue, 5 Jan 2021 12:34:41 +0100 [thread overview]
Message-ID: <20210105113446.16027-2-huobean@gmail.com> (raw)
In-Reply-To: <20210105113446.16027-1-huobean@gmail.com>
From: Bean Huo <beanhuo@micron.com>
Current EM macro definition, we use stringize operator '#', which turns
the argument it precedes into a quoted string. Thus requires the symbol
of __print_symbolic() should be the string corresponding to the name of
the enum.
However, we have other cases, the symbol and enum name are not the same,
we can redefine EM/EMe, but there will introduce some redundant codes.
This patch is to remove this restriction, let others reuse the current
EM/EMe definition.
