ksmbd: fix passing freed memory 'aux_payload_buf'
[ Upstream commit59d8d24f46
] The patche2b76ab8b5
: "ksmbd: add support for read compound" leads to the following Smatch static checker warning: fs/smb/server/smb2pdu.c:6329 smb2_read() warn: passing freed memory 'aux_payload_buf' It doesn't matter that we're passing a freed variable because nbytes is zero. This patch set "aux_payload_buf = NULL" to make smatch silence. Fixes:e2b76ab8b5
