Use the FIELD_PREP() helper, instead open-coding the same operation.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Compile-tested only.
See "[PATCH 00/17] Non-const bitfield helper conversions" (https://lore.kernel.org/r/cover.1637592133.git.geert+renesas@glider.be) for background and more conversions. --- drivers/regulator/lp87565-regulator.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
