cpusensor: Search in peci-0 directory
The code was searching /sys/bus/peci/devices for PECI sensors. This results in below directories to be searched on typical 2 socket x86 systems. * peci-0 * 0-30 * 0-31 Where 0-30 and 0-31 exist in peci-0 as well. It is unnecessary, and the files in 0-30 and 0-31 will be searched twice because they exist in peci-0. Change the code to search in /sys/bus/peci/devices/peci-0 to make sure it only search the files within the expected directory. Note that the current peci driver only create peci-0, this code could be easily extended to support peci-1/2/3 in the future. Tested: The time for cpusensor to search the peci sensors reduces from 0.5s to about 0.3s. Signed-off-by: Lei YU <[email protected]> Change-Id: I7b0f3ad7bea7a3dced13a985f0ad19ffda33f6d2
