These macros use the equivalent of "#define WL_<type>(x) printk x" which requires an extra level of parentheses. Convert the macros to use the normal WL_<type>(fmt, args...) style and remove the extra parentheses from the uses. Add format argument verification using no_printk as appropriate. Couple of spelling typo fixes in the formats and argument alignment at the same time. Also coalesced long formats.

Broadcom Mac80211 driver This is a driver in progress. It has features still to be implemented well as bugs in current code. What's here and not here ======================= - Completely open source host driver, no binary object files - Features Broadcom's OneDriver architecture (single source base for supported chips and architectures) - On-chip firmware loaded using standard request_firmware() - Support for BCM43224, BCM43225, BCM4313 (PCIe NIC) - Framework for supporting new chips, including mac80211-aware embedded chips - Does not support older PCI/PCIe chips with SSB backplane - Driver includes BMAC interface for transparent dongle support - Uses minstrel_ht rate algorithm - HW based encryption not enabled yet What's done ========== - Integration with mac80211 stack - A-MPDU single & dual stream rates - BCM43224: Dualband, Dual stream, 20MHz channels Throughput (in chamber): ~85-90 Mbits/sec (in both 2.4 & 5 GHz bands) - BCM43225: 2.4 GHz, Dual Stream, 20MHz channels Throughput (in chamber): ~85-90 Mbits/sec - BCM4313: 2.4 GHz, Single Stream Throughput (in chamber): ~40 Mbits/sec Things To Be Done ================= See the TODO file Firmware installation ====================== Firmware is available from the Linux firmware repository at: git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git https://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git For all chips, copy brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw to /lib/firmware/brcm (or wherever firmware is normally installed on your system). Currently supported chips ============== PCI Name Device ID BCM4313 0x4727 BCM43224 0x4353 BCM43225 0x4357 Bugs/Problems ============== - Driver can get confused while scanning during high throughput, can cause burping, hanging, and possible crashing. - Occasional hangs & burps with BCM43224 on 2.4 GHz with dual stream rates. - Occasional crashes with BCM43224 on multicore machines. Note on Regulatory Implementation ================================ This generation of chips contain additional regulatory support independent of the driver. The devices use a single worldwide regulatory domain, with channels 12-14 (2.4 GHz band) and channels 52-64 and 100-140 (5 GHz band) restricted to passive operation. Transmission on those channels is suppressed until appropriate other traffic is observed on those channels. Within the driver, we use the ficticious country code "X2" to represent this worldwide regulatory domain. There is currently no interface to configure a different domain. The driver reads the SROM country code from the chip and hands it up to mac80211 as the regulatory hint, however this information is otherwise unused with the driver.
