| |
Hello,
I am testing a source analysis tool (http://repo.or.cz/w/smatch.git) and it generates a warning in dsp_cmx_send_member().
The problem is that on line 1327 we verify that dsp->conf is non null but on line 1329 we assume that it is non null and dereference it without checking.
drivers/isdn/mISDN/dsp_cmx.c 1327 if (dsp->conf && dsp->conf->software && dsp->conf->hardware) 1328 tx_data_only = 1; 1329 if (dsp->conf->software && dsp->echo.hardware) 1330 tx_data_only = 1;
regards, dan carpenter
