drivers/media/platform/sti/hva/hva-v4l2.c:43:22: warning: symbol 'hva_encoders' was not declared. Should it be static?
drivers/media/platform/sti/hva/hva-v4l2.c:1401:24: warning: symbol 'hva_driver' was not declared. Should it be static?

Make these static.

ba4616b7d9 [media] st-hva: add H.264 video encoding support
This patch adds the H.264 video encoding capability in the V4L2 HVA
video encoder driver for STMicroelectronics SoC (hva-h264.c).

The main supported features are:
- profile: baseline, main, high, stereo high
- level: up to 4.2
- bitrate mode: CBR, VBR
- entropy mode: CABAC, CAVLC
- video aspect: 1x1 only

57b2c0628b [media] st-hva: multi-format video encoder V4L2 driver
This patch adds V4L2 HVA (Hardware Video Accelerator) video encoder
driver for STMicroelectronics SoC. It uses the V4L2 mem2mem framework.

This patch only contains the core parts of the driver:
- the V4L2 interface with the userland (hva-v4l2.c)
- the hardware services (hva-hw.c)
- the memory management utilities (hva-mem.c)

This patch doesn't include the support of specific codec (e.g. H.264)
video encoding: this support is part of subsequent patches.
