Subject: [PATCH v1 2/5] interconnect: qcom: Move qcom_icc_xlate_extended() to a common file
Date: Sat, 16 Apr 2022 23:40:10 +0800	[thread overview]
Message-ID: <20220416154013.1357444-3-leo.yan@linaro.org> (raw)
In-Reply-To: <20220416154013.1357444-1-leo.yan@linaro.org>

since there have conflict between two headers icc-rpmh.h and icc-rpm.h,
the function qcom_icc_xlate_extended() is declared in icc-rpmh.h thus
it cannot be used by icc-rpm driver.

Move the function to a new common file icc-common.c so that allow it to
be called by multiple drivers.
