+Subject: [PATCH] rtlwifi: Fix build errors for unusual cases
+
+The present build configuration for the rtlwifi family of drivers will
+fail under two known conditions:
+
+(1) If rtlwifi is selected without selecting any of the dependent drivers,
+    there are errors in the build.
+(2) If the PCI drivers are built into the kernel and the USB drivers are modules,
+    or vice versa, there are missing globals.
+
+The first condition is fixed by never building rtlwifi unless at least one
+of the device drivers is selected. The second failure is fixed by splitting
+the PCI and USB codes out of rtlwifi, and creating their own mini drivers.
+If the drivers that use them are modules, they will also be modules.
+
+Although a number of files are touched by this patch, only Makefile and Kconfig
+have undergone significant changes. The only modifications to the other files
+were to export entry points needed by the new rtl_pci and rtl_usb units, or to
+rename two variables that had names that were likely to cause namespace collisions.
