From 9cc1b39f5af840ba728f613a68a45778f22cdf82 Mon Sep 17 00:00:00 2001 From: Artur Weber Date: Fri, 7 Feb 2025 21:02:41 +0100 Subject: [PATCH] pinctrl: bcm281xx: Fix incorrect regmap max_registers value [ Upstream commit 68283c1cb573143c0b7515e93206f3503616bc10 ] The max_registers value does not take into consideration the stride; currently, it's set to the number of the last pin, but this does not accurately represent the final register. Fix this by multiplying the current value by 4.
