The tracepoint can't be used in code section where we are in the
middle of a state transition.
For example if we place a tracepoint inside start/stop_critical_section(),
lockdep complains with

This work is based on work by Daniel Wagner. A few tracepoints are added
at the end of the critical section. With the hist trigger in place, the
hist trigger plots may be generated, with per-cpu breakdown of events

Is the structure

you do PIO to endpoint 0 but DMA to the others?
Could you resend the series?

Device driver for Mellanox I2C controller logic, implemented in Lattice CPLD

Device supports:
- Master mode
- One physical bus
- Polling mode
The Kconfig currently controlling compilation of this code is:
drivers/i2c/busses/Kconfig:config I2C_MLXCPLD
of_match_device could return NULL, and so cause a NULL pointer
dereference later.
For fixing this problem, we use of_device_get_match_data(), this will
simplify the code a little by using a standard function for
getting the match data.
Testing the return value of of_device_get_match_data is also

I have here a FPGA behind PCIe which exports SRAM which I use for
pstore. Now it seems that the FPGA no longer supports cmpxchg based
updates and writes back 0xff…ff and returns the same. This leads to
crash during crash rendering pstore useless.

This is extremely confusing when monitoring the same workload across

This patch enables getting a HPD GPIO descriptor quickly.
The exynos-hdmi driver uses "hpd" for HDMI hot plug detection.

It's actually a crash of the program doing the perf_event_open() call, not
a crash of the system (at least in my experience).
However, it's possible that
