Hello Tony Lindgren,
This is a semi-automatic email about new static checker warnings.
The patch be88c16a22ed: "OMAPDSS: panel sharp-ls037v7dw01 DT support"
from May 16, 2014, leads to the following Smatch complaint:
drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c:113 sharp_ls_enable()
error: we previously assumed 'ddata->vcc' could be null (see line 105)
drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c
104
105 if (ddata->vcc) {
^^^^^^^^^^
Check.
106 r = regulator_enable(ddata->vcc);
107 if (r != 0)
108 return r;
109 }
110
111 r = in->ops.dpi->enable(in);
112 if (r) {
113 regulator_disable(ddata->vcc);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Unchecked dereference inside function.
114 return r;
115 }
regards,
dan carpenter
