From 2668dba6df53584fb147d656c45a600d9e723dcb Mon Sep 17 00:00:00 2001 From: Zhenzhong Duan Date: Wed, 11 Mar 2020 15:16:54 +0800 Subject: [PATCH] misc: move FLASH_MINOR into miscdevice.h and fix conflicts FLASH_MINOR is used in both drivers/char/nwflash.c and drivers/sbus/char/flash.c with conflict minor numbers. Move all the definitions of FLASH_MINOR into miscdevice.h. Rename FLASH_MINOR for drivers/char/nwflash.c to NWFLASH_MINOR and FLASH_MINOR for drivers/sbus/char/flash.c to SBUS_FLASH_MINOR.
