[PATCH] selftests/intel_pstate: fix operand expected

[PATCH] selftests/intel_pstate: fix operand expected

[Alessandro Zanni]

This fix solves these errors, when calling kselftest with
targets "intel_pstate":

- ./run.sh: line 90: / 1000: syntax error: operand expected
(error token is "/ 1000")
- ./run.sh: line 92: / 1000: syntax error: operand expected
(error token is "/ 1000")

To error was found by running tests manually with the command:
make kselftest TARGETS=intel_pstate

What is "calling" kselftest? Please include the command you
ran in the change log.

Also, say "Fix" instead of "This fix"

Running "command" results in the following errors:

<errors>

Fix them

"To" -> These?

Why not just move this up:

I don't see any errors when I run the above command on Linux 6.12-rc3
What's you environment like?
