X-Git-Tag: v2.6.27-rc4~101^2~19 X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-linux.git;a=commitdiff_plain;h=7839b5162d7d6c100f70a036be1e1f2b072857bc usb: isp1760: don't be noisy about short packets. According to Alan Stern, short packets are quite normal under certain circumstances. This printk was triggered by usb to serial converters on every packet and some usb sticks triggered a few of those while plugging the stick. This printks are now hidden unless USB debug mode is activated.
