      usb: misc: usb3503: Fix compile error due to incorrect regmap depedency · eea88512
      Matthew Dawson authored
      The USB3503 driver had an incorrect depedency on REGMAP, instead of
      REGMAP_I2C.  This caused the build to fail since the necessary regmap
      i2c pieces were not available.

      Fix this so at least we can continue booting and get to a shell prompt.
