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 drivers/gpio/gpiolib.c | 26 +++++++++++++++++++++++--- drivers/gpio/gpiolib.h | 1 + drivers/nvmem/core.c | 14 ++++++++++---- include/linux/gpio/consumer.h | 1 + 4 files changed, 35 insertions(+), 7 deletions(-) -- 2.25.0
