usb-misc: sisusbvga: Fix coding style: horizontal whitespace changes
This patch fixes whitespace coding style issues that can be fixed
within a single line. This patch fixes the following checkpatch
warnings:
- 83 ERROR: space required after that ','
- 13 ERROR: switch and case should be at the same indent
- 08 WARNING: please, no spaces at the start of a line
- 03 ERROR: space required before the open parenthesis '('
- 04 WARNING: suspect code indent for conditional statements
- 01 WARNING: space prohibited between function name and open parenthesis
- 01 ERROR: spaces required around that '='
- 01 ERROR: code indent should use tabs where possible
