[PATCH] Fix usage of true and false as field names in struct taint_flag

[Valdis Kletnieks]

commit 7fd8329ba502ef76dd91db561c7aed696b2c7720
Author: Petr Mladek <pmla...@suse.com>

    taint/module: Clean up global and module taint flags handling

Contains this chunk:

--- a/include/linux/kernel.h

+struct taint_flag {
+       char true;      /* character printed when tainted */
+       char false;     /* character printed when not tainted */
+       bool module;    /* also show as a per-module taint flag */
+};

and hilarity ensues when an out-of-tree module has this:

# ifndef true
#  define true  (1)
# endif
# ifndef false
#  define false (0)
# endif

Change the field names to not shadow something likely to be used
by third-party modules.
