[Dan Carpenter]

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

   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		}
