Subject: [PATCH] fix opendir fails in check_platform_device
|
|
|
|
When irq name does not contain spaces, savedptr is an empty string and irq_fullname will have a extra space at the end like "
|
|
LNRO0005:00 ".
|
|
So opendir in check_platform_device will fail, and irqbalance prints log:
|
|
"No directory /sys/devices/platform/LNRO0005:00 /: No such file or directory"
