Subject: sizeof *data, when data isn't initalized, is that right?
Date: Thu, 22 Jan 2015 16:19:54 -0200 [thread overview]
Message-ID: <54C13F4A.2020404@gmail.com> (raw)
I came across this code:
struct mcp23s08_driver_data *data;
...
data = kzalloc(sizeof *data + chips * sizeof(struct mcp23s08),
GFP_KERNEL);
Since data wasn't initialized when `sizeof *data' is called, wasn't this a non-initialized pointer dereference?
Cheers
