* param: make parameter functions more consistentSascha Hauer2017-04-111-6/+6
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* efi: only iterate over handles that provide the device path protocolMichael Olbrich2017-03-301-2/+4

* efi: load the protocol expected by the driverMichael Olbrich2017-03-301-3/+4
| | | | | | | | | | The drivers are loaded if any guid provided by the device matches. So load the protocol for the matched guid and not for the first guid. Otherwise the driver may cast the protocol to the wrong type and proably crash. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
