[PATCH 1/2] staging: dgap: fix possible NULL dereference

2015-09-10 Thread Sudip Mukherjee
The return pointer from dgap_getword() is used in strcmp() where it is dereferenced. But dgap_getword() can return NULL. Lets put a check there and return 0 as error. Signed-off-by: Sudip Mukherjee --- drivers/staging/dgap/dgap.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/stag
