Subject: linux-next: build failure after merge of the extcon tree

Hi all,

After merging the extcon tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/extcon/extcon-max14526.c: In function 'max14526_probe':
drivers/extcon/extcon-max14526.c:252:74: error: conversion from 'long unsigned int' to 'unsigned int' changes value from '18446744073709551614' to '4294967294' [-Werror=overflow]
  252 |         regmap_write_bits(priv->regmap, MAX14526_CONTROL_2, USB_DET_DIS, ~USB_DET_DIS);
cc1: all warnings being treated as errors

Caused by commit

  0367e6929cf6 ("extcon: Add basic support for Maxim MAX14526 MUIC")

18446744073709551614 is 0xFFFFFFFFFFFFFFFE.

I have used the extcon tree from next-20250505 for today.
