Earlier today I suggested fixing this by adding an empty implementation of of_match_device, but I forgot that an .of_match pointer has been added to struct device for exactly this purpose. You can use that instead. That change is currently in mainline, but it has not been backported to the Linaro 2.6.38 tree (yet). g. > > This patch is to fix the error. > > Signed-off-by: Shawn Guo <shawn....@linaro.org> > --- > drivers/net/fec.c | 13 ++++++++++++- > 1 files changed, 12 insertions(+), 1 deletions(-) > > diff --git a/drivers/net/fec.c b/drivers/net/fec.c > index b57f879..ffb1e75 100644 > --- a/drivers/net/fec.c > +++ b/drivers/net/fec.c > @@ -85,8 +85,19 @@ static const struct of_device_id fec_dt_ids[] = { > { .compatible = "fsl,imx51-fec", .data = &fec_devtype[0], }, > {}, > }; > + > +static const struct of_device_id * > +fec_get_of_device_id(struct platform_device *pdev) > +{ > + return of_match_device(fec_dt_ids, &pdev->dev); > +} > #else > #define fec_dt_ids NULL > +static inline struct of_device_id * > +fec_get_of_device_id(struct platform_device *pdev) > +{ > + return NULL; > +} > #endif > > static unsigned char macaddr[ETH_ALEN]; > @@ -1380,7 +1391,7 @@ fec_probe(struct platform_device *pdev) > struct resource *r; > const struct of_device_id *of_id; > > - of_id = of_match_device(fec_dt_ids, &pdev->dev); > + of_id = fec_get_of_device_id(pdev); > if (of_id) > pdev->id_entry = (struct platform_device_id *)of_id->data; > > -- > 1.7.1 > > > _______________________________________________ > linaro-dev mailing list > linaro-dev@lists.linaro.org > http://lists.linaro.org/mailman/listinfo/linaro-dev _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
