Merge tag 'linux-cpupower-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux

Merge cpupower utility updates for 6.18-rc1 from Shuah Khan:

"Fixes incorrect return vale in cpupower_write_sysfs() error path
 and passing incorrect size to cpuidle_state_write_file() while
 writing status to disable file in cpuidle_state_disable()."
