  There is a error message within devm_ioremap_resource
  already, so remove the dev_err call to avoid redundant
  error message.

  In case of error, the function devm_clk_get() returns ERR_PTR()
  and not returns NULL. The NULL test in the return value check
  should be replaced with IS_ERR().

  The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
  It is able to handle video decoding/encoding of in a range of formats.
  The driver provides with VPU firmware download, memory management and
  the communication interface between CPU and VPU.
  For VPU initialization, it will create virtual memory for CPU access and
  IOMMU address for vcodec hw device access. When a decode/encode instance
  opens a device node, vpu driver will download vpu firmware to the device.
  A decode/encode instant will decode/encode a frame using VPU
  interface to interrupt vpu to handle decoding/encoding jobs.
