Hi,

The function clk_round_rate() is defined to return a "long", not an
"unsigned long". That's because it might return a negative error
code. Change the call in geni_se_clk_tbl_get() to check for errors.
While we're at it, get rid of a useless init of "freq".

The geni_se_clk_freq_match() has some strange semantics. Specifically
it is defined with two modes:
1. It can find a clock that's an exact multiple of the requested rate
2. It can find a non-exact match but it can't handle multiples then
...but callers should always be able to handle a clock

This patch fixes pin assign of vcc_host1_5v. This regulator is
controlled by USB20_HOST_DRV signal.
ROCK64 schematic says that GPIO0_A2 pin is used as USB20_HOST_DRV.
GPIO0_D3 pin is for SPDIF_TX_M0.

Hi,
While fuzzing arm64 v4.19-rc2 with Syzkaller, I'm seeing a number of
splats (e.g. use-after-frees) in tty ioctl handling, e.g.
n_tty_set_termios. I've included one such splat at the end of this email.
It looks like syzbot has been hitting these (e.g. [1]) for a number of months,
so I guess

This fixes two bugs:
- The first one is a side effect caused by using SRCU for rcuidle

tracepoints to make RCU watch when it wasn't. The real fix will
be to have perf use SRCU instead of depending on RCU watching,

Linus,
This fixes two bugs:
- The first one is a side effect caused by using SRCU for rcuidle
tracepoints. It seems that perf was depending on the rcuidle
tracepoints to make RCU watch when it wasn't. The real fix will
be to have perf use SRCU instead of depending on RCU watching,

I'm sorry, this case is not good to demonstrate the useage. And I think
there are no other people will do the test without MCE in
