    ARM: 8654/1: decompressor: add strlen prototype · 7b96ddd0

    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():

    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.
