thunderbolt: Capitalize comment on top of QUIRK_FORCE_POWER_LINK_CONTROLLER

2020-09-16T11:57:46Z

To keep it consistent with the other single line comments in the driver. Signed-off-by: Mika Westerberg

thunderbolt: Correct tb_check_quirks() kernel-doc

2020-09-16T11:57:46Z

Remove extra white space and make the sentence end with a period. Signed-off-by: Mika Westerberg

thunderbolt: Log correct zeroX entries in decode_error()

2020-09-16T11:57:46Z

There was copy & paste error so it always printed value of pkg->zero1. Also use tb_ctl_warn() here, no need to print backtrace. Signed-off-by: Mika Westerberg

thunderbolt: Handle ERR_LOCK notification

2020-09-16T11:57:46Z

If the USB4 router downstream port is locked, sending configuration packet to a router below it causes ERR_LOCK to be sent. Instead of warn splat about unknown error we log the error (just warning level) and return -EACCESS instead. The idea is that we may want to do something when such error code is received, like perform unlock. Signed-off-by: Mika Westerberg

thunderbolt: Use "if USB4" instead of "depends on" in Kconfig

2020-09-16T11:57:46Z

This groups the USB4 options more nicely, and also does not require that every config option lists explicit depends on USB4. Signed-off-by: Mika Westerberg

thunderbolt: Allow KUnit tests to be built also when CONFIG_USB4=m

2020-09-16T11:57:46Z

This adds a bit more build coverage for the tests even though these are not expected to be enabled by normal users and distros. In order to make this working we need to open-code kunit_test_suite() and call the relevant functions directly in the driver init/exit hook. Signed-off-by: Mika Westerberg

thunderbolt: Only stop control channel when entering freeze

2020-09-16T11:57:46Z

According to the kernel power management documentation freeze phase should only quiesce the device, no need to configure wakes or put it to low power state. For this reason we simply stop the control channel and in case of Software Connection Manager also mark the hotplug disabled. This should align the driver better with the PM framework expectations.

thunderbolt: debugfs: Fix uninitialized return in counters_write()

2020-09-10T16:39:56Z

If the first line is in an invalid format then the "ret" value is uninitialized. We should return -EINVAL instead. Fixes: 54e418106c76 ("thunderbolt: Add debugfs interface") Signed-off-by: Dan Carpenter Signed-off-by: Mika Westerberg
