From 8f5e24514cbd63c352b663636f955fb286f2c3bd Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire <hofrat@osadl.org> Date: Sat, 11 May 2019 02:56:33 +0200 Subject: [PATCH] net: qrtr: use protocol endiannes variable sparse was unable to verify endiannes correctness due to reassignment from le32_to_cpu to the same variable - fix this warning up by providing a proper __le32 type and initializing it. This is not actually fixing any bug - rather just addressing the sparse warning. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: David S.
