Subject: [PATCH] of: Make explicit cpu_to_be32 conversion to mute sparse warning
Kernel test robot reports sparse warning:
sparse warnings: (new ones prefixed by >>)
>> drivers/of/base.c:1337:73: sparse: sparse: incorrect type in initializer
(different base types) @@ expected restricted __be32 @@ got int @@
drivers/of/base.c:1337:73: sparse: expected restricted __be32
drivers/of/base.c:1337:73: sparse: got int
Thus, Make explicit conversions to mute warning(Although BE and LE are
exactly same in binary representation for 0/~0).
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202402042134.GEb3Bgwl-lkp@intel.com/
