Currently seq_buf_puts() will happily create a non null-terminated
string for you in the buffer. This is particularly dangerous if the
buffer is on the stack.
For example:
char buf[8];
char secret = "secret";
struct seq_buf s;
seq_buf_init(&s, buf, sizeof(buf));
seq_buf_puts(&s, "foo")
Jann Horn points out that we're using unsigned int for len in
seq_buf_puts(), which could potentially overflow if we're passed a
UINT_MAX sized string.
The rest of the code already uses size_t, so we should also use that
in seq_buf_puts() to avoid any issues.

Commit 4d3ebd3658d8 ("coreisght: tmc: Claim device before use") uses
CLAIM tag to validate if the device is available, it needs to pass

Hi, Sudeep,
I use MIPS, and there is no "size" in
/sys/devices/system/cpu/cpuX/cache/indexX/ file after your patch. Because the
DT node only has "next-level-cache = <&L2>;" but has no "size" information.
