Fixes for omaps for v5.8-rc cycle
Few fixes for issues noticed during testing: - Two DEBUG_ATOMIC_SLEEP fixes for ti-sysc interconnect target module driver - A regression fix for ti-sysc no-idle handling that caused issues compared to earlier platform data based booting - A fix for memory leak for omap_hwmod_allocate_module - Fix d_can driver probe for am437x -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAl8PUn4RHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXN7XRAA0PRDhYAQF9OoeWL337gf0fXRchYA42Pk C5R5KXdkSZZOlexWCsnmXGBIfAgup2B9sBTr6kFWQW1oPAIzO2oF/ALkw0U+aMsd A5UMKOmHJCaHwMyiHu2kpwnTFCRUFdGpTYsCxOxAjFgk8R8YdSD2xnWnDwdgJSDX Lk2SQ+ycfRf1aDT06UaSiwn1vQAOmMOEi0SV4KpyO4eH93mRjsNB7N2aUcKeq2m/ y4JLBF486QCJjJg91YG4wHoM/4O/fIeDWH2nGW2C3BU9f6F7uDip31mNBMB8ra2R 7ijIxLnQRypB5fgCEjimQ+2wWE2Mt1NRfxaIu2Kc9dZxmjqknzEV7oFQg48bQbtQ X7K8idTFyvdlhMZS9ajKpbbrxSGLqo53sgLWJHCNC0QBFX0clHmcWXrwZn6BNtbr lQ/+u6lFRthN6jQzudxf3nI/W68yskmfKWnVl5TEkA8tctxyZYjl5Td6DRLCI988 f23NKqTAssgHH5MWR5jDpJrZSThlty9ZqRWLjTON4rYeqVM5vXKtieSIDpV5ZmFo VYVdv43tg4wnKBFLWZUurVmXhVmlawzsVyAAG83XkjNmPcQCGpI4sByGtujltLGQ Bo6EwgMo3aOi9sKMOiEviAHhZbzxjLGwqt13L3b/9NX0e9T14gKhil9WswQpSkZ0 UnB5N2rwOUU= =ekbH -----END PGP SIGNATURE----- Merge tag 'omap-for-v5.8/fixes-rc5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fixes for omaps for v5.8-rc cycle Few fixes for issues noticed during testing: - Two DEBUG_ATOMIC_SLEEP fixes for ti-sysc interconnect target module driver - A regression fix for ti-sysc no-idle handling that caused issues compared to earlier platform data based booting - A fix for memory leak for omap_hwmod_allocate_module - Fix d_can driver probe for am437x * tag 'omap-for-v5.8/fixes-rc5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Fix dcan driver probe failed on am437x platform ARM: OMAP2+: Fix possible memory leak in omap_hwmod_allocate_module bus: ti-sysc: Do not disable on suspend for no-idle bus: ti-sysc: Fix sleeping function called from invalid context for RTC quirk bus: ti-sysc: Fix wakeirq sleeping function called from invalid context Link: https://lore.kernel.org/r/pull-1594840100-132735@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
