[PATCH] btrfs: fix type of parameter generation in btrfs_get_dentry

by David Sterba

The type of parameter generation has been u32 since the beginning, however all callers pass a u64 generation, so unify the types to prevent potential loss.

[PATCH] ASoC: qcom: SND_SOC_SC7180 optionally depends on SOUNDWIRE

[PATCH] counter: microchip-tcb-capture: Handle Signal1 read and Synapse

by William Breathitt Gray

The signal_read(), action_read(), and action_write() callbacks have been assuming Signal0 is requested without checking. This results in requests for Signal1 returning data for Signal0. This patch fixes these oversights by properly checking for the Signal's id in the respective callbacks and handling accordingly based on the particular Signal requested. The trig_inverted member of the mchp_tc_data is removed as superfluous.

[PATCH AUTOSEL 4.19 01/25] wifi: brcmfmac: fix invalid address access when enabling SCAN log level

From: Wright Feng <wright.feng(a)cypress.com> [ Upstream commit aa666b68e73fc06d83c070d96180b9010cf5a960 ] The variable i is changed when setting random MAC address and causes invalid address access when printing the value of pi->reqs[i]->reqid.

[PATCH 2/2] drm/connector: send hotplug uevent on connector cleanup

by Simon Ser

A typical DP-MST unplug removes a KMS connector. However care must be taken to properly synchronize with user-space. The expected sequence of events is the following: 1. The kernel notices that the DP-MST port is gone. 2. The kernel marks the connector as disconnected, then sends a uevent to make user-space re-scan the connector list. 3. User-space notices the connector goes from connected to disconnected, disables it. 4. Kernel handles the the IOCTL disabling the connector. On success, the very last reference to the struct drm_connector is dropped and drm_connector_cleanup() is called. 5. The connector is removed from the list, and a uevent is sent to tell user-space that the connector disappeared. The very last step was missing. As a result, user-space thought the connector still existed and could try to disable it again. Since the kernel no longer knows about the connector, that would end up with EINVAL and confused user-space. Fix this by sending a hotplug uevent from drm_connector_cleanup().
