The dw_hdmi enable/disable handling is particularly weak in several regards: * The hotplug interrupt could call hdmi_poweron() or hdmi_poweroff() while DRM is setting a mode, which could race with a mode being set. * Hotplug will always re-enable the phy whenever it detects an active hotplug signal, even if DRM has disabled the output. Resolve all of these by introducing a mutex to prevent races, and a state-tracking bool so we know whether DRM wishes the output to be enabled. We choose to use our own mutex rather than ->struct_mutex so that we can still process interrupts in a timely fashion. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |
