V4L/DVB (5373): [PATCH] Hauppauge Nova-T endianess problem on powerpc
When trying to use a Hauppauge Nova-T Stick on a big-endian architecture (such as powerpc) no frontend can be attached. The attached patch fixes this problem by removing two lines in dib0700_ctrl_rd() that try to correct the endianess on two values that already are correct: - /* think about swapping here */ - value = le16_to_cpu(value); - index = le16_to_cpu(index); With this simple patch this dvb hardware works great, thanks to anyone involved for the good work. :) Signed-off-by: Dennis Ranke <mail@exoticorn.de> Signed-off-by: Patrick Boettcher <pb@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
