[PATCH] staging: ccree: fix type mismatch warning

From: Arnd Bergmann
Date: Thu Dec 21 2017 - 08:31:57 EST


__dump_byte_array used to be hidden, but is now visible to the compiler
and causes a harmless warning:

drivers/staging/ccree/ssi_driver.c:82:6: error: conflicting types for '__dump_byte_array'
drivers/staging/ccree/ssi_driver.c: In function '__dump_byte_array':
drivers/staging/ccree/ssi_driver.c:89:41: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'size_t {aka unsigned int}' [-Werror=format=]

This changes the prototype in the header to match that of the actual
function on all architectures, and the format string to match the
argument.

Fixes: 3f268f5d6669 ("staging: ccree: turn compile time debug log to params")
