[PATCH v3 0/3] HID: nvidia-shield: Fix the error handling path of shield_probe()
From: Rahul Rameshbabu
Date: Mon Sep 18 2023 - 07:58:57 EST
This series fixes some missing clean-up function calls in the error handling of
the probe.
Patch 1 and 2 fix some similar issues introduced in 2 different commits (hence 2
patches)
Patch 3 is an enhancement that creates a common function for cleaning up
thunderstrike instances.
Changes:
v1->v2:
- Add the LED_RETAIN_AT_SHUTDOWN flag to prevent
led_classdev_unregister from trying to set the LED to off before a
successful call to hid_hw_start.
- Rename err_haptics label to err_ts_create to make the label name more
accurate.
- Re-order operations in thunderstrike_destroy to be in LIFO order with
regards to the operations in thunderstrike_create.
v2->v3:
- Refactor thunderstrike_destroy to take a thunderstrike instance
pointer as a parameter and prevent a variable from being unused
in shield_probe.

Notes from Rahul:
- Thank you so much Christophe for these patches.
- Sent v2 without accounting for the fact that thunderstrike_destroy in v1
makes the thunderstrike instance in shield_probe unused. Tested v3 with W=1.
