-Subject: [PATCH] phy: marvell: comphy: Convert internal SMCC firmware return
- codes to errno
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Driver ->power_on and ->power_off callbacks leaks internal SMCC firmware
-return codes to phy caller. This patch converts SMCC error codes to
-standard linux errno codes. Include file linux/arm-smccc.h already provides
-defines for SMCC error codes, so use them instead of custom driver defines.
-Note that return value is signed 32bit, but stored in unsigned long type
-with zero padding.
