      [media] smiapp: Remove set_xclk() callback from hwconfig · e62c30e7
      Sakari Ailus authored
      The clock framework is generally so well supported that there's no reason
      to keep this one around.

      The clock may be provided by a driver which is yet to probe. Print the
      actual error code as well.

      [media] cx231xx: can't proceed if I2C bus register fails · 461af077
      Mauro Carvalho Chehab authored
      The driver should not ignore errors while registering the I2C
      bus, as this device can't even minimally work without the buses,
      as it uses those buses internally to talk with the several IP
      blocks inside the chip.

      [media] cx231xx-i2c: handle errors with cx231xx_get_i2c_adap() · 4001dfb4
      Mauro Carvalho Chehab authored
      The cx231xx_get_i2c_adap() function should return the I2C
      adapter that will be used to talk with a device. It should never
      be NULL, as otherwise the driver will try to dereference a
      null pointer.
      
      We might instead fix the callers, but if this condition
      ever happens, it is really a driver bug, because i2c_port
      should always be a value from enum CX231XX_I2C_MASTER_PORT.
      
      Found when checking the code due to this bug:

      This device uses GPIOs: 28 to switch between analog and

      The code that sets it on analog mode is OK, but it misses
      the logic that sets it on digital mode.
