| H A D | driver.h | 959bc7b2 Tue Nov 07 12:15:59 CST 2017 Thierry Reding <treding@nvidia.com> gpio: Automatically add lockdep keys
In order to avoid lockdep boilerplate in individual drivers, turn the
gpiochip_add_data() function into a macro that creates a unique class
key for each driver.
Note that this has the slight disadvantage of adding a key for each
driver registered with the system. However, these keys are 8 bytes in
size, which is negligible and a small price to pay for generic
infrastructure.
