From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> stable inclusion from stable-v6.6.33 commit 32f615e0a580db81a289544ce8251510efdf7b0e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 41e1cd1401fcd1f1ae9e47574af2d9fc44a870b3 ] In a way similar to the previous commit, move typec_partner_set_usb_power_delivery() to be called after reading the PD caps. This also removes calls to usb_power_delivery_unregister_capabilities() from the error path. Keep all capabilities registered until they are cleared by ucsi_unregister_partner_pdos().
