There doesn't seem to be a devm_bitmap_zalloc > FYI I've implemented both devm_bitmap_zalloc() as well as devm_bitmap_alloc() and made them part of a series I sent out to linux-gpio two weeks ago (surprisingly - it's nowhere to be found on lkml or spinics or even patchwork :/). The patches didn't make it for v5.12 but I'll respin them after the merge window, so we'll have those devres helpers for v5.13. Bartosz
