pm2fb: source code improvements
PATCH 1/1 pm2fb: source code improvements
From: Krzysztof Helt <[email protected]>
This patch concentrates on source compacting, simplification and more conformance to kernel coding standards. The major changes:
- RD32() and WR() functions are merged into pm2_RD() and pm2_WR()
- conditional (with switch()) RDAC functions are separated in two unconditional ones
- the conditional pm2fb_block_op() function is merged into pm2fb_fillrect() and pm2fb_copyarea()
- WAIT_FIFO() values are corrected
---
This patch requires all previously sent pm2fb patches (mm tree and pm2fb-mttr and pm2fb-imageblit-full).

This patch concentrates on source compacting, simplification and more conformance to kernel coding standards. The major changes:
- RD32() and WR() functions are merged into pm2_RD() and pm2_WR()
- conditional (with switch()) RDAC functions are separated in two unconditional ones
- the conditional pm2fb_block_op() function is merged into pm2fb_fillrect() and pm2fb_copyarea()
- WAIT_FIFO() values are corrected
