Because gpiochip_add_data successfully done, use
err_remove_gpiochip instead of err_free_bitmap to free
such as gdev,descs..

Please use get_maintainers.pl - you have not put neither Linus nor I

What does 'gdev,desc.' stand for (also notice dot at the end)?

Perhaps you also want to add this
ae495810cffe ("gpio: regmap: add the .fixed_direction_output configuration parameter")

As the patch changed the logic from the original commit.

Interestingly the 3bd44edd6c55 ("gpio: regmap: fix memory leak of gpio_regmap
structure") fixed one leak and missed this one.

Hello Andy,

I noticed it in v6.6.117, i fogot rebase it in v6.19-rc1, i will send v2 soon.

PS: The fact is we need to call gpiochip_remove(chip) to free what gpiochip_add_data(chip, gpio) alloc.
