mfd: da9055: Remove MODULE_LICENSE in non-modules 2023-04-26T10:40:31+00:00 Nick Alcock nick.alcock@oracle.com 2023-03-08T19:42:54+00:00 1247f3c3e1f29fc78027dfe4043f6c0413612126 Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

While powering up DA9055, both power sequencer and gpio events are received. These events remain uncleared after boot up, due to which further event handling also fails. DA9055 has three event registers. The event register bits are set to '1' on receiving an event. The events can be cleared on writing a '1' to the set bit, which would then clear that bit to '0'. After applying this patch we have a clean state after boot up.
