crypto: tegra: fix size_t format string

[PATCH] crypto: tegra: fix size_t format string

Posted by Arnd Bergmann 9 months, 1 week ago

From: Arnd Bergmann <arnd@arndb.de>

Printing size_t as %lu causes a warning when it is defined as 'unsigned int':

drivers/crypto/tegra/tegra-se-hash.c:344:22: error: format specifies type 'unsigned long' but the argument has type 'ssize_t' (aka 'int') [-Werror,-Wformat]
  343 |         dev_dbg(se->dev, "msg len %llu msg left %llu sz %lu cfg %#x",
      |                                                         ~~~
      |                                                         %zd

Use %zu as the proper format string.
