When building a 32-bit kernel, the following warnings will appear:
scripts/dtc/checks.c: In function ‘check_simple_bus_reg’:
scripts/dtc/checks.c:876:41: warning: format ‘%zx’ expects argument of type ‘size_t’, but argument 4 has type ‘uint64_t {aka long long unsigned int}’ [-Wformat=]
snprintf(unit_addr, sizeof(unit_addr), %zx, reg);
^
scripts/dtc/checks.c:876:41: warning: format ‘%zx’ expects argument of type ‘size_t’, but argument 4 has type ‘uint64_t {aka long long unsigned int}’ [-Wformat=]
This patch fixes it.
