| |
Changed the memory and resource allocations in the probe function to devm. Also added a remove callback.
Signed-off-by: Nicolas Frayer <nfrayer@baylibre.com> ---
v2->v3: dropped module conversion part of this series while other driver dependencies on socinfo are worked out. A dependency issue is introduced by changing subsys_initcall() to module_platform_driver(). Some drivers using the socinfo information probe before the socinfo driver itself and it makes their probe fail.
Dropped series: https://lore.kernel.org/all/20221010131538.7333-1-nfrayer@baylibre.com/
