Subject: [PATCH v2 0/2] gpio: cdev: label sanitization fixes
Date: Thu,  4 Apr 2024 11:33:26 +0200	[thread overview]
Message-ID: <20240404093328.21604-1-brgl@bgdev.pl> (raw)

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

This series fixes a couple of bugs in the sanitization of labels
being passed to irq.

Patch 1 fixes the case where userspace provides empty labels.

Patch 2 fixes a missed path in the sanitization changes that can result
in memory corruption.

v1 -> v2:
- switched the order of the patches in order to avoid introducing buggy
  code in one just to fix it in the second

Bartosz Golaszewski (1):
  gpio: cdev: check for NULL labels when sanitizing them for irqs

Kent Gibson (1):
  gpio: cdev: fix missed label sanitizing in debounce_setup()
