[PATCH v2 0/2] staging: vt6656: Cleanup of the vnt_get_frame_time function

[Oscar Carter]

This patch series makes a cleanup of the vnt_get_frame_time function.

The first patch makes use of the define RATE_11M instead of a magic
number. The second patch remove unnecessary local variable initialization.

Changelog v1 -> v2
- Not use the ARRAY_SIZE macro to compare against the tx_rate variable.

[PATCH 1/2] staging: vt6656: Use define instead of magic number for tx_rate

[Oscar Carter]

Use the define RATE_11M present in the file "device.h" instead of the
magic number 3. So the code is more clear.

[PATCH 2/2] staging: vt6656: Remove unnecessary local variable initialization

[Oscar Carter]

Don't initialize the rate variable as it is set a few lines later.

Don't review this patch series as I have sent a new version. Sorry.
