Subject: [PATCH] net: qrtr: Mark 'buf' as little endian
Date: Mon, 9 Jan 2017 14:31:58 -0800 [thread overview]
Message-ID: <20170109223158.29255-1-sboyd@codeaurora.org> (raw)
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: warning: incorrect type in assignment (different base types)
net/qrtr/qrtr.c:275:16: expected unsigned int [unsigned] [usertype] <noident>
net/qrtr/qrtr.c:275:16: got restricted __le32 [usertype] <noident>
net/qrtr/qrtr.c:276:16: warning: incorrect type in assignment (different base types)
net/qrtr/qrtr.c:276:16: expected unsigned int [unsigned] [usertype] <noident>
net/qrtr/qrtr.c:276:16: got restricted __le32 [usertype] <noident>
Silence it.
