2021-06-03MIPS: ralink: export rt_sysc_membase for rt2880_wdt.cRandy Dunlap
[ Upstream commit fef532ea0cd871afab7d9a7b6e9da99ac2c24371 ] rt2880_wdt.c uses (well, attempts to use) rt_sysc_membase. However, when this watchdog driver is built as a loadable module, there is a build error since the rt_sysc_membase symbol is not exported. Export it to quell the build error. ERROR: modpost: "rt_sysc_membase" [drivers/watchdog/rt2880_wdt.ko] undefined!
