Subject[PATCH 09/15] rpmsg: smd: Drop unnecessary condition for channel creation
Date
From: Vladimir Lypak <vladimir.lypak@gmail.com>

RPM Firmware on variety of newer SoCs such as MSM8917 (also likely
MSM8937, MSM8940, MSM8952), MSM8953 and on some MSM8916 devices) doesn't
initiate opening of the SMD channel if it was previously opened by
bootloader. This doesn't allow probing of smd-rpm driver on such devices
because there is a check that requires RPM this behaviour.
