Hello Mauro Carvalho Chehab,
This is a semi-automatic email about new static checker warnings.
The patch a7d44baaed0a: "[media] cx23885-dvb: Remove a dirty hack
that would require DVBv3" from Dec 26, 2011, leads to the following
Smatch complaint:
drivers/media/video/cx23885/cx23885-dvb.c +135 cx23885_dvb_gate_ctrl()
error: we previously assumed 'fe' could be null (see line 128)
drivers/media/video/cx23885/cx23885-dvb.c
127
128 if (fe && fe->dvb.frontend && fe->dvb.frontend->ops.i2c_gate_ctrl)
^^
Old condition.
129 fe->dvb.frontend->ops.i2c_gate_ctrl(fe->dvb.frontend, open);
130
131 /*
132 * FIXME: Improve this path to avoid calling the
133 * cx23885_dvb_set_frontend() every time it passes here.
134 */
135 cx23885_dvb_set_frontend(fe->dvb.frontend);
^^^^
New dereference.
136 }
137
regards,
dan carpenter
