USB: iowarrior.c: timeouts too small in usb_control_msg calls
The driver uses usb_control_msg() for exchanging data with the device. When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the timeouts for these calls where set to 5*HZ for reading, 1HZ for writing. (These timeouts seemed to work fine for all users of the driver, at least nobody complained in the last 2 years. The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and left the driver with 5 jiffies for reading and 1 jiffy for writing. My new machine is fast, but not that fast. The patch also removes a useless debug statement, which was left over from testing a broken firmware version From: Eberhard Fahle <e.fahle@wayoda.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
