Subject: [PATCH v6 2/2] ath9k: htc: clean up statistics macros
I've changed *STAT_* macros a bit in previous patch and I seems like
they become really unreadable. Align these macros definitions to make
code cleaner and fix folllowing checkpatch warning
ERROR: Macros with complex values should be enclosed in parentheses
Also, statistics macros now accept an hif_dev as argument, since
macros that depend on having a local variable with a magic name
don't abide by the coding style.
No functional change
Suggested-by: Jeff Johnson <quic_jjohnson@...cinc.com>

Changes since v4:
- Fixed build error caused by wrong variable name
passed to newly added macros
Changes since v4:
- Rebased on top of ath-next branch
Changes since v3:
- Added additional clean up related to relying on magical
name from outside of the macro
Changes since v2:
- My send-email script forgot, that mailing lists exist.
Added back all related lists
- Fixed checkpatch warning
Changes since v1:
- Added this patch
