Subject: PROBLEM: Ali m5602 won't compile (3.4.9-gentoo)

  Hello,

  I have trouble compiling the 3.4.9 kernel with genkernel (gentoo)
having enabled the Ali Corp webcam (m5602) driver.

  Here's the output of the ver_linux script:

=================================

  My current kernel configuration is attached to this mail. What I
tried to do, was to enable the Ali Corp webcam (m5602) driver using
menuconfig as follows:

  Device Drivers --->
    <*> Multimedia Support --->
      <*> Video For Linux (NEW)
      [*] Video capture adapters (NEW) --->
        [*] V4L USB devices (NEW) --->
          <*> GSPCA based webcams (NEW) --->
            <*> Ali USB m5602 Camera Driver

  Here's the relevant output of genkernel:
