Re: dvb_usb_rtl2831u module cause "oops" on kernel 2.6.32 when loading

[Thomas Holzeisen <thomas@holzeisen.de>]

Hi Jan,

this looks great. At first the checkout did not build throwing me this error:

> /usr/src/rtl2831-r2/v4l/ir-sysfs.c: In function 'store_protocols':
> /usr/src/rtl2831-r2/v4l/ir-sysfs.c:137: error: implicit declaration of function 'skip_spaces'
> /usr/src/rtl2831-r2/v4l/ir-sysfs.c:137: warning: assignment makes pointer from integer without a cast
> /usr/src/rtl2831-r2/v4l/ir-sysfs.c:178: warning: assignment makes pointer from integer without a cast

i replaced the file by an older version from a previous checkout and then it build perfectly. It 
also gets initialized without a flaw:

I am normally not using the included IR, but testing revealed its working as well.
