If anyone has any objections, please let me know. ------------------ From: Forest Bond commit f1b00f4dab29b57bdf1bc03ef12020b280fd2a72 upstream. Commit d83579e2a50ac68389e6b4c58b845c702cf37516 incorporated some changes from the vendor driver that made it newly important that the calculated hardware version correctly include the CHIP_92D bit, as all of the IS_92D_* macros were changed to depend on it. However, this bit was being unset for dual-mac, dual-phy devices. The vendor driver behavior was modified to not do this, but unfortunately this change was not picked up along with the others. This caused scanning in the 2.4GHz band to be broken, and possibly other bugs as well. This patch brings the version calculation logic in parity with the vendor driver in this regard, and in doing so fixes the regression. However, the version calculation code in general continues to be largely incoherent and messy, and needs to be cleaned up.
