From 33d5e332b9c5ce0bf3bfd44ca2127d1773b3f2ad Mon Sep 17 00:00:00 2001 From: Giuseppe CAVALLARO Date: Thu, 7 Jun 2012 19:25:07 +0000 Subject: stmmac: fix driver built w/ w/o both pci and platf modules The commit ba27ec66ffeb78cbf fixes the Kconfig of the driver when built as module allowing to select/unselect the PCI and Platform modules that are not anymore mutually exclusive. This patch fixes and guarantees that the driver builds on all the platforms w/ w/o PCI and when select/unselect the two stmmac supports. In case of there are some problems on both the configuration and the pci/pltf registration the module_init will fail. v2: set the CONFIG_STMMAC_PLATFORM enabled by default. I've just noticed that this can actually help on some configurations that don't enable any STMMAC options by default (e.g. SPEAr). v3: change printk level when do not register the driver.
