[PATCH v2 2/2] soundwire: intel: use {u32|u16}p_replace_bits

Vinod Koul vkoul at kernel.org
Thu Sep 17 14:01:46 CEST 2020


FIELD_PREP() does not replace the bits so it is not apt in case where we
modify a register.

Use u32_replace_bits() or u16_replace_bits() instead.

Fixes: 3b4979cabd4b ("soundwire: intel: use FIELD_{GET|PREP}")
