[PATCH 0/3] gpio: Failure path fixes
From: Geert Uytterhoeven
Date: Thu Mar 28 2019 - 09:13:55 EST
Hi Linus, Bartosz,
After making a silly mistake in a pin control driver, pinctrl driver
initialization failed, causing an avalanche of GPIO driver failures, and
I was greeted by the following scary messages:
OF: ERROR: Bad of_node_put() on /soc/gpio@e6050000
...
WARNING: CPU: 0 PID: 1 at lib/refcount.c:156 kobject_get+0x38/0x4c
...
WARNING: CPU: 0 PID: 1 at lib/refcount.c:190 refcount_sub_and_test_checked+0x3c/0xa8
The first two patches fix bugs in related error paths, after which the
messages are gone.
The third patch is a drive-by fix for function comment.
Thanks for your comments!
Geert Uytterhoeven (3):
gpio: of: Fix of_gpiochip_add() error path
gpio: Fix gpiochip_add_data_with_key() error path
gpio: Remove obsolete comment about gpiochip_free_hogs() usage

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
