It was just too much hassle to deal with. These days I tend to report more bugs instead of fixing them myself. I run on linux-next and complain to the original author as soon as the buggy code is merged. If the code is old, then my experience is that no one will fix it. Also 5000 inconsistent NULL checks seems like too high of a figure. For my inconsistent NULL checks I get 215 of these warnings: sound/i2c/other/ak4xxx-adda.c:808 build_adc_controls() error: we previously assumed 'ak->adc_info' could be null (see line 789) And 75 of these: fs/efs/inode.c:298 efs_map_block() warn: variable dereferenced before check 'bh' (see line 292) regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
