Should appear in v3.12 (or a fixed version anyway) - please let me know if it works for you.

Dear Mark Brown,

Hi Mark. How have you been.

I am JS Park in Samsung System Audio Engineer.

I have question about regimap register function.

We can set default register to call regmap_register_pattch function= .

but, see the below source code, It is possible just one time.

If need change defualt register, like as wm1811_reva_patch, I have to mo= dify wm8994-core.c

Is it imposible not to change wm8994 driver source?

I just want to add custmize default regiister setting for Samsung specif= y register regarding earphone detection.

@drivers/base/regmap/regmap.c

int regmap_register_patch(struct regmap *map,= const struct reg_default *regs,
