Robert Jarzmik b3802db5eb mmc: pxamci: fix potential oops ... As reported by Dan in his report in [1], there is a potential NULL pointer derefence if these conditions are met : - there is no platform_data provided, ie. host->pdata = NULL Fix this by only using the platform data ro_invert when a gpio for read-only is provided by the platform data. This doesn't appear yet as every pxa board provides a platform_data, and calls pxa_set_mci_info() with a non NULL pointer. [1] [bug report] mmc: pxamci: fix card detect with slot-gpio API. The commit fd546ee6a7 ("mmc: pxamci: fix card detect with slot-gpio API") from Sep 26, 2015, leads to the following static checker warning: drivers/mmc/host/pxamci.c:809 pxamci_probe() warn: variable dereferenced before check 'host->pdata' (see line 798) Fixes: fd546ee6a7 ("mmc: pxamci: fix card detect with slot-gpio API") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>		2016-07-18 11:50:40 +02:00
