media: meson/ao-cec: move cec_notifier_cec_adap_register after hw setup [ Upstream commit 3e84a18a259e1df35e5b549ab92ec3baf82ff010 ] When probed after the HDMI notifier, calling cec_notifier_cec_adap_register() calls the enable() adapter callback, but the HW is not yet set up. Moving cec_notifier_cec_adap_register() right before cec_register_adapter() fixes the following crash: Ignoring spurious kernel translation fault at virtual address 0000000000000008 [...] Hardware name: Khadas VIM (DT) [...] pc : __do_kernel_fault+0xdc/0x120 lr : __do_kernel_fault+0xdc/0x120 [...] Call trace: __do_kernel_fault+0xdc/0x120 do_page_fault+0x180/0x458 do_translation_fault+0x64/0x70 do_mem_abort+0x3c/0x98 el1_da+0x20/0x94 meson_ao_cec_adap_enable+0x30/0x218 [ao_cec] __cec_s_phys_addr+0x184/0x270 cec_s_phys_addr+0x44/0x60 cec_notifier_cec_adap_register+0x68/0x90 meson_ao_cec_probe+0xb0/0x288 [ao_cec] [...] el0_svc_compat+0x8/0x10 Reported-by: Christian Hewitt <christianshewitt@gmail.com> Suggested-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Fixes: 20958f9d5c48 ("media: meson/ao-cec: use cec_notifier_cec_adap_(un)register") Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
