slimbus: ngd: Fix build error on x86

2018-11-27T07:44:06+00:00

on non DT platforms like x86 of_match_node is set to NULL, dereferencing
directly would throw an error.
Fix this by doing this in two steps, get the match then the data.

slimbus: ngd: remove unnecessary check

2018-11-07T13:59:28+00:00

SLIM_MSG_CLK_PAUSE_SEQ_FLG is never set in any of the slim core,
so performing a check in ngd driver is totally unnecessary.

Also this patch fixes warning about mc field overflow reported
with CoverityScan.

Making clk pause feature optional will be added to slim core in
next development cycle.

slimbus: ngd: mark PM functions as __maybe_unused

2018-09-14T13:36:20+00:00

qcom_slim_ngd_runtime_suspend is protected by an #ifdef,
qcom_slim_ngd_runtime_idle is now, which causes a build time warning:

drivers/slimbus/qcom-ngd-ctrl.c:1470:12: error: 'qcom_slim_ngd_runtime_idle' defined but not used [-Werror=unused-function]

Marking both as __maybe_unused lets us get rid of the warning
as well as the #ifdef.
