Merge tag 'regmap-fix-v6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fix from Mark Brown:
"The I2C bus was not taking account of the register and any padding
bytes when handling maximum write sizes supported by an I2C adaptor,
this patch from Jim Wylder fixes that"
