usb: gadget: rndis: use signed type for a signed value

2015-05-21T21:29:14Z

rndis_get_nr() returns either a non-negative value on success or a negative value on failure. In case of failure an error code is returned to the caller of rndis_register(). If the "i" is unsigned, the information about error from rndis_get_nr() is lost. If there is no error but rndis_get_nr() returns a value greater than 256 the least significant bits of i are zero effectively limiting the number of configs to 256. This patch fixes that.

Don't use a space between function name and parameter list opening bracket. All other functions in this file comply wich checkpatch rules. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi

usb: gadget: rndis: use rndis_params instead of configNr

2015-05-07T18:46:54Z

RNDIS function has a limitation on the number of allowed instances. So far it has been RNDIS_MAX_CONFIGS, which happens to be one. In order to eliminate this kind of arbitrary limitation we should not preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params instances but instead allow allocating them on demand. This patch prepares the elimination of the said limit by converting all the functions which accept rndis config number to accept a pointer to the actual struct rndis_params. Consequently, rndis_register() returns a pointer to a corresponding struct rndis_params instance. The pointer is then always used by f_rndis.c instead of config number when it talks to rndis.c API. A nice side-effect of the changes is that many lines of code in rndis.c become shorter and fit in 80 columns. If a function prototype changes in rndis.h a style cleanup is made at the same time, otherwise checkpatch complains that the patch has style problems.

usb: gadget: Gadget directory cleanup - group usb functions

2014-07-16T17:50:36Z

The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the USB functions implementations into a separate directory. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi
