This reverts commit 5bdb102. Brian Norris <computersforpeace@gmail.com> is reporting: Ralf, Please revert this and send it to Linus (or else, I can send it myself). This is causing build failures, because I didn't take the rest of Simon's series yet. drivers/mtd/bcm63xxpart.c: In function 'bcm63xx_parse_cfe_partitions': drivers/mtd/bcm63xxpart.c:93:2: error: implicit declaration of function 'bcm63xx_nvram_get_psi_size' [-Werror=implicit-function-declaration] Signed-off-by: Ralf Baechle <ralf@linux-mips.org> References: https://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=20160126191607.GA111152%40google.com
