ide: ide-taskfile.c fix style problems
Browse files Browse the repository at this point in the history 
Fix trivial style problems:

WARNING: Use #include <linux/uaccess.h> instead of <asm/uaccess.h>
WARNING: space prohibited between function name and open parenthesis '('
WARNING: EXPORT_SYMBOL(foo); should immediately follow its function/variable
ERROR: do not use C99 // comments X 2
ERROR: trailing statements should be on next line
ERROR: trailing whitespace
ERROR: switch and case should be at the same indent
WARNING: line over 80 characters

total: 5 errors, 4 warnings

Also removed dead code

Also used pr_err() to avoid line breaks
