[mythtv-users] Enabling experimental ATRPMS

[Cory Papenfuss]

 	DOH!  I saw your post yesterday but was confused as to the intent. 
The compat.h applied, but not the ivtv-firmware.c patch.  Did you patch against 
a vanilla ivtv-0.1.10-pre2-ck100z?

[mythtv at localhost driver]$ pwd
/home/mythtv/ivtv-0.1.10-pre2-ck100z/driver

[mythtv at localhost driver]$ patch -p2 < ivtv-firmware.c.patch
patching file ivtv-firmware.c
Hunk #1 FAILED at 95.
1 out of 1 hunk FAILED -- saving rejects to file ivtv-firmware.c.rej

[mythtv at localhost driver]$ head ivtv-firmware.c.rej
***************
*** 95,136 ****
         return 0;
   }

   static int load_fw_direct(const char *fn, char *mem)
   {
-         int fd;
           long l;
-       mm_segment_t fs = get_fs();


I don't speak "diff-ese" yet... :)
