Subject: [PATCH AUTOSEL for 4.9 17/54] net: qrtr: Mark 'buf' as little endian

From: Stephen Boyd <sboyd@...eaurora.org>

[ Upstream commit 3512a1ad56174308a9fd3e10f4b1e3e152e9ec01 ]

Failure to mark this pointer as __le32 causes checkers like
sparse to complain:

net/qrtr/qrtr.c:274:16: warning: incorrect type in assignment (different base types)
net/qrtr/qrtr.c:274:16:    expected unsigned int [unsigned] [usertype] <noident>
net/qrtr/qrtr.c:274:16:    got restricted __le32 [usertype] <noident>

net/qrtr/qrtr.c:275:16:    got restricted __le32 [usertype] <noident>

Silence it.
