From: J. German Rivera Date: Wed, 6 Jan 2016 22:03:24 +0000 (-0600) Subject: staging: fsl-mc: Changed DPRC built-in portal's mc_io to be atomic X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1129cde59d08afd91fb2baed66824eb2dbd079aa;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: fsl-mc: Changed DPRC built-in portal's mc_io to be atomic The DPRC built-in portal's mc_io is used to send commands to the MC to program MSIs for MC objects. This is done by the fsl_mc_msi_write_msg() callback, which is invoked by the generic MSI layer with interrupts disabled. As a result, the mc_io used in fsl_mc_msi_write_msg needs to be an atomic mc_io. Signed-off-by: J.
