Merge patch series "Enable / require DEVRES for devm_.alloc usage outside xPL"
Tom Rini <[email protected]> says:
As seen by a number of patches fixing memory leaks, U-Boot has a problem
with developer expectations around devm_kmalloc and friends. Namely,
whereas in Linux these memory allocations will be freed automatically in
most cases, in U-Boot this is only true if DEVRES is enabled. Now,
intentionally, in xPL phases, we do not (and do not offer as an option)
enabling DEVRES. However in full U-Boot this is left either to the user,
or some drivers have select'd DEVRES on their own. This inconsistency is
a problem. This series goes and deals with two small issues that were
shown by having all drivers that use devm_.alloc to allocate memory also
select DEVRES and then we make DEVRES no longer be a prompted option and
instead select'd as needed. We do not make this unconditional as it
would result in growing the resulting binary on the many platforms which
have no users of the devm_.alloc family of functions.
