Subject: [PATCH 0/6] nvmem/gpio: fix resource management

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

This series addresses a couple problems with memory management in nvmem
core. We fix an earlier memory leak in error path in patch 2/6. Patches
1/6, 5/6 & 6/6 add reference counting to gpio_desc structure and use it
to correctly free the write-protect GPIO. Patches 3/6 & 4/6 fix newline
problems.

Bartosz Golaszewski (5):
  gpiolib: use kref in gpio_desc
  nvmem: fix memory leak in error path
  nvmem: remove a stray newline in nvmem_register()
  nvmem: add a newline for readability
  nvmem: increase the reference count of a gpio passed over config

Khouloud Touil (1):
  nvmem: release the write-protect pin
