Subject: [PATCH 5.10 239/593] regulator: fan53880: Fix vsel_mask setting for FAN53880_BUCK

From: Axel Lin <axel.lin@...ics.com>

[ Upstream commit 2e11737a772b95c6587df73f216eec1762431432 ]

According to the datasheet:
REGISTER DETAILS − 0x02 BUCK, BUCK_OUT is BIT0 ~ BIT7.

So vsel_mask for FAN53880_BUCK should be 0xFF.
