Subject: [Suggestion] Bluetooth: hidp: redundant initialization or issue for function hidp_copy_session
Date: Tue, 07 May 2013 22:08:09 +0800 [thread overview]
Message-ID: <51890AC9.7010501@asianux.com> (raw)
In-Reply-To: <518906A8.7060708@asianux.com>
Hello Maintainers:
In net/bluetooth/hidp/core.c, for hidp_copy_session(), the
'session->input' and 'session->hid' are conflict with each other.
And excuse me, I do not quit know the details, but I think we have 2
choices for fixing it:
one is ''if (session->input) { } else if (session->hid) { };''
the other is ''if (seesion->hid) { } else if (session->input) { };''
The first choice assumes the original code has a logical issue; the
second choice assumes the original code has redundant initialization.
Please help check.
Thanks.
71 static void hidp_copy_session(struct hidp_session *session, struct hidp_conninfo *ci)
72 {
73 memset(ci, 0, sizeof(*ci));
74 bacpy(&ci->bdaddr, &session->bdaddr);
75
76 ci->flags = session->flags;
77 ci->state = BT_CONNECTED;
78
79 ci->vendor = 0x0000;
80 ci->product = 0x0000;
81 ci->version = 0x0000;
82
83 if (session->input) {
84 ci->vendor = session->input->id.vendor;
85 ci->product = session->input->id.product;
86 ci->version = session->input->id.version;
87 if (session->input->name)
88 strncpy(ci->name, session->input->name, 128);
89 else
90 strncpy(ci->name, "HID Boot Device", 128);
91 }
92
93 if (session->hid) {
94 ci->vendor = session->hid->vendor;
95 ci->product = session->hid->product;
96 ci->version = session->hid->version;
97 strncpy(ci->name, session->hid->name, 128);
98 }
99 }
