From: Nicolas Dichtel Date: Thu, 15 Nov 2012 04:06:41 +0000 (+0000) Subject: sit: fix sparse warnings X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d440b72068bb8dff3cc1c2a05b61e60843d82494;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git sit: fix sparse warnings This change fixes several sparse warnings about endianness problem. The wrong nla_*() functions were used. It also fix a sparse warning about a flag test (field i_flags). This field is used in this file like a local flag only, so it is more an u16 (gre uses it as a be16). This sparse warning was already there before the patch that add netlink management, the code has just been moved. Reported-by: Fengguang Wu Signed-off-by: Nicolas Dichtel Signed-off-by: David S.
