From 91d967497f11dbb5038c7b84bc30dae684ae5ffb Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 4 May 2017 12:30:07 -0500 Subject: [PATCH] of: fix sparse warnings in of_find_next_cache_node sparse gives a warning that 'handle' is not a __be32: ../drivers/of/base.c:2261:61: warning: incorrect type in argument 1 (different base types) ../drivers/of/base.c:2261:61: expected restricted __be32 const [usertype] *p ../drivers/of/base.c:2261:61: got unsigned int const [usertype] *[assigned] handle We could just change the type, but the code can be improved by using of_parse_phandle instead of open coding it with of_get_property and of_find_node_by_phandle.
