Subject: [PATCH 3/4] tools/csr_usb: Fix compilation failure

GCC's "format-nonliteral" security check is enabled as an error in
recent versions of Fedora. Given the reduced scope of use, mark the
error as ignorable through pragma.

tools/csr_usb.c: In function 'read_value':
tools/csr_usb.c:82:2: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
  n = fscanf(file, format, &value);
