openwrt怎么打补丁呀

ps3wifi

由于openwrt不支持sd，找到一遍文章说是要打补丁，我已经按照作者所说拷到 [color=rgb(3, 102, 214) !important]target/linux/ramips/patches-4.14/500-hack-mt76x8-pinctrl-esdmode.patch，但编译的时候还是出错提示mipsel-openwrt-linux-musl-cpp: error: ../dts/_alfa-network_awusfree1.dts: No such file or directory
mipsel-openwrt-linux-musl-cpp: warning: '-x assembler-with-cpp' after last input file has no effect
mipsel-openwrt-linux-musl-cpp: fatal error: no input files

请问各位大佬这个该怎么处理

		Subject: [PATCH] ramips: hack: add esdmode pinctrl group
		Since mt76x8an ver1 eco2, SDXC pins can be switched to the
		following pinmap:
		sd_d1  -> PAD_I2S_SDI
		sd_d0  -> PAD_I2S_WS
		sd_cmd -> PAD_I2S_CLK
		sd_d3  -> PAD_I2C_SCLK
		sd_d2  -> PAD_I2C_SD
		sd_clk -> PAD_GPIO0
		sd_wp  -> PAD_TXD1
		sd_cd  -> PAD_RXD1
		To use this pinmap, one would need to set ESD_MODE bit (bit 15)
		to 1 in GPIO1_MODE and switch other used pads into GPIO mode.
		MTK called this pinmap "router mode" and the pinmap described
		in their datasheed is called "iot mode".
		This patch is hacky because:
		1. pinmux-rt2880 doesn't support reserving noncontiguous GPIO
		pins so those GPIOs can't be properly reserved.
		2. it misused "gpio" function for "iot mode", due to the fact
		that this mode doesn't reserve any GPIOs.
