From: Arnd Bergmann Date: Thu, 8 May 2014 13:52:15 +0000 (+0200) Subject: usb: musb: tusb-dma can't be built-in if tusb is not X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=70c1ff4b3c865a36f00aa2498eab3eadd818e4ab;p=openwrt%2Fstaging%2Fblogic.git usb: musb: tusb-dma can't be built-in if tusb is not A configuration with CONFIG_USB_MUSB_HDRC=y, CONFIG_USB_TUSB_OMAP_DMA=y and CONFIG_USB_MUSB_TUSB6010=m causes a link failure because of the dependency on the tusb_get_revision symbol: (.text+0x154ce8): undefined reference to `tusb_get_revision' This patch ensures that either MUSB_HDRC and MUSB_TUSB6010 are both modules or both built-in, which are the valid configurations.
