From 96cb989857ddfe176f5d5258fbf750bb818c6500 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 16 Jun 2014 15:13:24 +0200 Subject: [PATCH] dmaengine: Update documentation for inline wrappers During the last few years, several inline wrappers for DMA operations have been introduced: - commit 16052827d98fbc13c31ebad560af4bd53e2b4dd5 ("dmaengine/dma_slave: introduce inline wrappers"), - commit a14acb4ac2a1486f6633c55eb7f7ded07f3ec9fc ("DMAEngine: add dmaengine_prep_interleaved_dma wrapper for interleaved api"), - commit 6e3ecaf0ad49de0bed829d409a164e7107c02993 ("dmaengine: add wrapper functions for device control functions"). Update the documentation to use the wrappers.
