Up to now, when endpoint addresses in descriptors were non-consecutive, there were created redundant files, which could cause problems in kernel, when user tried to read/write to them. It was result of fact that maximum endpoint address was taken as total number of endpoints in function. This patch adds endpoint descriptors counting and storing their addresses in eps_addrmap to verify their cohesion in each speed. Endpoint address map would be also useful for further features, just like vitual endpoint address mapping.

The variable $(PWD) is useless, and it may break the compilation. For example, it breaks the kernel compilation when it's done with buildroot : /home/trem/Codes/armadeus/armadeus/buildroot/output/host/usr/bin/ccache /home/trem/Codes/armadeus/armadeus/buildroot/output/host/usr/bin/arm-buildroot-linux-uclibcgnueabi-gcc -Wp,-MD,drivers/usb/gadget/legacy/.hid.o.d -nostdinc -isystem /home/trem/Codes/armadeus/armadeus/buildroot/output/host/usr/lib/gcc/arm-buildroot-linux-uclibcgnueabi/4.7.3/include -I./arch/arm/include -Iarch/arm/include/generated -Iinclude -I./arch/arm/include/uapi -Iarch/arm/include/generated/uapi -I./include/uapi -Iinclude/generated/uapi -include ./include/linux/kconfig.h -D__KERNEL__ -mlittle-endian -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-dwarf2-cfi-asm -mabi=aapcs-linux -mno-thumb-interwork -mfpu=vfp -funwind-tables -marm -D__LINUX_ARM_ARCH__=5 -march=armv5te -mtune=arm9tdmi -msoft-float -Uarm -fno-delete-null-pointer-checks -O2 --param=allow-store-data-races=0 -Wframe-larger-than=1024 -fno-stack-protector -Wno-unused-but-set-variable -fomit-frame-pointer -fno-var-tracking-assignments -g -Wdeclaration-after-statement -Wno-pointer-sign -fno-strict-overflow -fconserve-stack -Werror=implicit-int -Werror=strict-prototypes -DCC_HAVE_ASM_GOTO -I/home/trem/Codes/armadeus/armadeus/buildroot/drivers/usb/gadget/ -I/home/trem/Codes/armadeus/armadeus/buildroot/drivers/usb/gadget/udc/ -I/home/trem/Codes/armadeus/armadeus/buildroot/drivers/usb/gadget/function/ -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(hid)" -D"KBUILD_MODNAME=KBUILD_STR(g_hid)" -c -o drivers/usb/gadget/legacy/hid.o drivers/usb/gadget/legacy/hid.c drivers/usb/gadget/epautoconf.c:23:26: erreur fatale: gadget_chips.h : Aucun fichier ou dossier de ce type This compilation line include : ..../buildroot/driver/usb/gadget but the real path is : ..../buildroot/output/build/linux-3.17-rc1/driver/usb/gadget Signed-off-by: NPhilippe Reynes <tremyfr@gmail.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

If the pending buffers in the queue could not be pushed to the udc endpoint we have to cancel the uvc_queue. Otherwise the gadget will get stuck on this error. This patch calls uvc_queue_cancel if usb_ep_queue failed.

This reverts commit a9232076. It introduced a dead lock, and did not fix anything. it made netif_tx_lock() be called in IRQ context, but in softirq context, the same lock is locked without disabling IRQ.
