ARM: 8654/1: decompressor: add strlen prototype
The decompress.c file contains a declaration for strstr() so we can include some compression library code. With the updated LZ4 implementation, we run into the same problem again for strlen(): In file included from ../include/linux/rcupdate.h:40:0, from ../include/linux/srcu.h:33, from ../include/linux/notifier.h:15, from ../include/linux/memory_hotplug.h:6, from ../include/linux/mmzone.h:749, from ../include/linux/gfp.h:5, from ../include/linux/kmod.h:22, from ../include/linux/module.h:13, from ../arch/arm/boot/compressed/../../../../lib/lz4/lz4_decompress.c:39, from ../arch/arm/boot/compressed/../../../../lib/decompress_unlz4.c:13, from ../arch/arm/boot/compressed/decompress.c:55: include/linux/cpumask.h: In function 'cpumask_parse': include/linux/cpumask.h:592:53: error: implicit declaration of function 'strlen';did you mean 'strstr'? [-Werror=implicit-function-declaration] This adds another declaration to work around the new problem.
