From 2095b1426c9c8088f7be28d70c6d7eb432640baa Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 16 Jun 2016 11:01:10 +0200 Subject: [PATCH] mwifiex: fix link error against sdio Calling sdio_claim_host() from the interface independent part of the mwifiex driver is not only a layering violation, but also causes a link error if MMC support is disabled, or if CONFIG_MMC=m and CONFIG_MWIFIEX=y: drivers/net/built-in.o: In function `mwifiex_fw_dpc': :(.text+0xff138): undefined reference to `sdio_claim_host' :(.text+0xff158): undefined reference to `sdio_release_host' The right way to do this is to have the sdio specific code in the sdio driver front-end, and we already have a callback pointer that we can use for this after exporting the generic fw download function from the core driver.
