Hello Toshiaki Yamane,
This is a semi-automatic email about new static checker warnings.
The patch d084610bb1e8: "staging/rts_pstor: Use pr_ or dev_ printks
in rtsx.c" from Sep 16, 2012, leads to the following Smatch complaint:
drivers/staging/rts_pstor/rtsx.c:396 rtsx_resume()
warn: variable dereferenced before check 'dev' (see line 394)
drivers/staging/rts_pstor/rtsx.c
393
394 dev_info(&dev->pci->dev, "Ready to resume\n");
^^^^^^^^^^^^^^
New dereference.
395
396 if (!dev) {
^^^^
Old check.
397 dev_err(&dev->pci->dev, "Invalid memory\n");
^^^^^^^^^^^^^^
Another new dereference.
398 return 0;
regards,
dan carpenter
