[PATCH v2] clk: qcom: gpucc-sm8350: Fix "initializer element is not constant" error

From: Nathan Chancellor
Date: Mon Jul 11 2022 - 13:41:15 EST


When building with clang or GCC older than 8, errors along the following
lines occur:

drivers/clk/qcom/gpucc-sm8350.c:111:2: error: initializer element is not a compile-time constant
gpu_cc_parent,
^~~~~~~~~~~~~
drivers/clk/qcom/gpucc-sm8350.c:126:2: error: initializer element is not a compile-time constant
gpu_cc_parent,
^~~~~~~~~~~~~
2 errors generated.

The C standard allows an implementation to accept other forms of
constant expressions, which GCC 8+ has chosen to do, but it is not
required. Just inline the initializer to resolve the error.

* Just inline the initializer, rather than using a macro (Dmitry).
