Subject: [PATCH] Staging: bcm: Clean up code in ioctl:
 IOCTL_BCM_EEPROM_REGISTER_READ

This patch verifies two conditions before executing
a kmalloc call. First, it checks to see that
IoBuffer.OutputLength is not greater than an
unsigned short. If so, an invalid value may be
returned. The second change is a check to make
sure IoBuffer.OutputLength is not equal to
zero. Which simply keeps this code inline with
the other ioctl, IOCTL_BCM_REGISTER_READ_PRIVATE.
