The attached patch work. There is still a problem. When the card is working the gpio is changing constantly, and generate a lot of debug output. saa7134[0]/ir: build_key gpio=0x1c14f mask=0x2f200 data=24 saa7134[1]/ir: build_key gpio=0x3b3c5 mask=0x2f200 data=55 saa7134[2]/ir: build_key gpio=0x13f326 mask=0x2f200 data=63 saa7134[0]/ir: build_key gpio=0x1c1d8 mask=0x2f200 data=24 saa7134[1]/ir: build_key gpio=0x13b34f mask=0x2f200 data=55 saa7134[2]/ir: build_key gpio=0x3f3ff mask=0x2f200 data=63 saa7134[0]/ir: build_key gpio=0x11c120 mask=0x2f200 data=24 saa7134[1]/ir: build_key gpio=0x3b33d mask=0x2f200 data=55 saa7134[2]/ir: build_key gpio=0x13f3e6 mask=0x2f200 data=63 saa7134[0]/ir: build_key gpio=0x11c1d8 mask=0x2f200 data=24 saa7134[1]/ir: build_key gpio=0x13b302 mask=0x2f200 data=55 saa7134[2]/ir: build_key gpio=0x3f350 mask=0x2f200 data=63 saa7134[0]/ir: build_key gpio=0x1c15b mask=0x2f200 data=24 saa7134[1]/ir: build_key gpio=0x3b3b7 mask=0x2f200 data=55 saa7134[2]/ir: build_key gpio=0x13f3cc mask=0x2f200 data=63 ...........................................
