Subject: [PATCH v2 01/12] dmaengine: fsl-edma: clean up EXPORT_SYMBOL_GPL in fsl-edma-common.c
Date: Mon, 29 May 2023 16:04:42 -0400 [thread overview]
Message-ID: <20230529200453.1423796-2-Frank.Li@nxp.com> (raw)
In-Reply-To: <20230529200453.1423796-1-Frank.Li@nxp.com>
Exported functions in fsl-edma-common.c are only used within
fsl-edma.c and mcf-edma.c. Global export is unnecessary.
This commit removes all EXPORT_SYMBOL_GPL in fsl-edma-common.c,
and renames fsl-edma.c and mcf-edma.c to maintain the same
final module names as before, thereby simplifying the codebase.
