[PATCH v1 1/2] gpiolib: legacy: Make sure we kill gpio_request_one() first
Posted by Andy Shevchenko 2 months, 3 weeks ago
Make sure we kill gpio_request_one() first by converting it to
use legacy APIs that will be alive a bit longer. In particular,
this also shows the code we will use in another function to make
it die independently.
