2019-02-26regulator: da9062: Use struct_size() in devm_kzalloc()Gustavo A. R. Silva1-4/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = alloc(size, GFP_KERNEL) Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = alloc(struct_size(instance, entry, count), GFP_KERNEL) Notice that, in this case, variable size is not necessary, hence it is removed.

commit e5e21f70bfd3 ("regulator: core: Take lock before applying system load") took the regulator lock before calling drms_uA_update() in order to silence a lockdep warning during regulator_register(). However, we are not supposed to need locks at this point as the regulator is in the process of being registered, so there should be no possibility of concurrent access. Instead, remove the unnecessary locking and simply drop the lockdep annotation, since it is no longer valid.

However, when SNVS is used we must not allow SW to control enabling/disabling those regulators which are crucial for system to boot as there is a HW limitation which causes SW controlled regulators to be kept shut down after SNVS reset. Allow setting the SNVS to be used as reset target state and allow marking those regulators which are critical for boot.

As a result of exporting the bd70528 specific locking functions we no longer need struct bd70528. Remove references to struct bd70528 from bd70528 regulator. Signed-off-by: Matti Vaittinen <[email protected]> Signed-off-by: Mark Brown <[email protected]>
