From: Randy Dunlap <rdunlap@infradead.org> stable inclusion from linux-4.19.207 commit 8d0a3d07bfa9518825cb4b71999f74bf50b3d557 -------------------------------- commit 7366c23ff492ad260776a3ee1aaabba9fc773a8b upstream. Building dp83640.c on arch/parisc/ produces a build warning for PAGE0 being redefined. Since the macro is not used in the dp83640 driver, just make it a comment for documentation purposes. In file included from ../drivers/net/phy/dp83640.c:23: ../drivers/net/phy/dp83640_reg.h:8: warning: "PAGE0" redefined 8 | #define PAGE0 0x0000 from ../drivers/net/phy/dp83640.c:11: ../arch/parisc/include/asm/page.h:187: note: this is the location of the previous definition 187 | #define PAGE0 ((struct zeropage *)__PAGE_OFFSET) Fixes: cb646e2b02b2 ("ptp: Added a clock driver for the National Semiconductor PHYTER.")
