[PATCH] a bug in linefeed removal

While I was adding pattern match to the LABEL method i hit a bug.
We modify a string returned from libsysfs, so with every iteration is is
truncated by one char:

Dec  4 02:27:16 pim udev[23307]: do_label: dev->bus='scsi' sysfs_device->bus='scsi'
Dec  4 02:27:16 pim udev[23307]: do_label: look for device attribute 'vendor'
Dec  4 02:27:16 pim udev[23307]: do_label: xxx 'IBM-ESXS '
Dec  4 02:27:16 pim udev[23307]: do_label: compare attribute 'vendor' value 'IBM-ESX' with '?IBM-ESXS'
Dec  4 02:27:16 pim udev[23307]: do_label: dev->bus='scsi' sysfs_device->bus='scsi'
Dec  4 02:27:16 pim udev[23307]: do_label: look for device attribute 'vendor'
Dec  4 02:27:16 pim udev[23307]: do_label: xxx 'IBM-ESX'
Dec  4 02:27:16 pim udev[23307]: do_label: compare attribute 'vendor' value 'IBM-ES' with 'IBM-ESXS?'
Dec  4 02:27:16 pim udev[23307]: do_label: dev->bus='scsi' sysfs_device->bus='scsi'
Dec  4 02:27:16 pim udev[23307]: do_label: look for device attribute 'vendor'
Dec  4 02:27:16 pim udev[23307]: do_label: xxx 'IBM-ES'
Dec  4 02:27:16 pim udev[23307]: do_label: compare attribute 'vendor' value 'IBM-E' with 'IBM-ES??'
Dec  4 02:27:16 pim udev[23307]: do_label: dev->bus='scsi' sysfs_device->bus='scsi'
Dec  4 02:27:16 pim udev[23307]: do_label: look for device attribute 'vendor'
Dec  4 02:27:16 pim udev[23307]: do_label: xxx 'IBM-E'
Dec  4 02:27:16 pim udev[23307]: do_label: compare attribute 'vendor' value 'IBM-' with 'IBM-ESXSS'

I changed the behavior to remove only the line feed.
