[PATCH] firmware: arm_scmi: replace resevered identifiers in macros

[PATCH] firmware: arm_scmi: replace resevered identifiers in macros

[trix]

From: Tom Rix <trix@redhat.com>

Identifiers starting with __ are resevered.  Replace __X with X.

The arguments to these macros are pointers.  The macros only reads
values.  There is no need to make copies of the pointers, use them
directly.

Fixes: a287126c31ab ("firmware: arm_scmi: Add configurable polling mode for transports")

Agreed and thanks for the patch.

However the original patch was modified and these macros were moved
to inline functions[0] after the initial build warnings from the
build bot[1]. Sorry my reply to the bot seems to have got lost and didn't
make it to the list.
