phy: mediatek: remove temporary variable @mask_

2023-02-02T13:05:13Z

Remove the temporary @mask_, this may cause build warning when use clang compiler for powerpc, but can't reproduce it when compile for arm64. the build warning is caused by: "warning: result of comparison of constant 18446744073709551615 with expression of type (aka 'unsigned long') is always false [-Wtautological-constant-out-of-range-compare]" More information provided in below lore link. After removing @mask_, there is a "CHECK:MACRO_ARG_REUSE" when run checkpatch.pl, but due to @mask is constant, no reuse problem will happen.

Due to FIELD_PREP() macro can be used to prepare a bitfield value, local ones can be remove; add the new helper to make bitfield update easier. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/20220920090038.15133-2-chunfeng.yun@mediatek.com Signed-off-by: Vinod Koul
