Subject[PATCH v3 08/10] drivers: qcom: rpmh-rsc: Don't double-check rpmh
Date
The calls rpmh_rsc_write_ctrl_data() and rpmh_rsc_send_data() are only
ever called from rpmh.c. We know that rpmh.c already error checked
the message. There's no reason to do it again in rpmh-rsc.

Suggested-by: Maulik Shah <mkshah@codeaurora.org>
Signed-off-by: Douglas Anderson <dianders@chromium.org>

Changes in v3:
- ("Don't double-check rpmh") replaces ("Warning if tcs_write...")

Changes in v2: None
