It's a one line fix, and pretty trivial to do yourself if you
I do think though the slightly odd wcn36xx_<level> uses of:
-#define wcn36xx_err(fmt, arg...) \
- printk(KERN_ERR pr_fmt("ERROR " fmt), ##arg);
-#define wcn36xx_warn(fmt, arg...) \
- printk(KERN_WARNING pr_fmt("WARNING " fmt), ##arg)
-#define wcn36xx_info(fmt, arg...) \
- printk(KERN_INFO pr_fmt(fmt), ##arg)
+#define wcn36xx_err(fmt, ...) \
+ pr_err("ERROR " fmt, ##__VA_ARGS__)
+#define wcn36xx_warn(fmt, ...) \
+ pr_warn("WARNING " fmt, ##__VA_ARGS__)
+#define wcn36xx_info(fmt, ...) \
+ pr_info(fmt, ##__VA_ARGS__)
should still be converted to more normal pr_<level> like I did.
I don't believe that prefixing of "ERROR " and "WARNING " to
pr_err and pr_warn actually gain anything as the same level
information can be got already with dmesg -r via the "<3>" and
"<4>" prefixes or dmesg -l3 -l4

Luis? Kalle? Other Qualcomm/Atheros folk?
One of the nominal benefits of separating the ath_<level>
macros by subsystem was perf/tracing. I believe some of the
ath subsystems have integrated the dmesg and tracing code.
I'm not sure how separable those may be here or if it's even
desirable to separate them. I'd guess not.
