Subject: use of dev->dev_t
Date: Tue, 17 Mar 2015 20:43:38 +0000	[thread overview]
Message-ID: <550891FA.1020007@postgrad.manchester.ac.uk> (raw)

Hi,
I am trying to write a driver that uses the MINOR(dev_t) to identify 
cards. Since it is a PCI driver and I get pcidev->dev.dev_t anyway. I 
thought about not bothering to store the minor number of the device.
However if I look at pcidev->dev.dev_t in the remove function (the 
driver frameworks remove), I always get pcidev->dev.dev_t == 0.

Is this the intended behaviour and if so why? (This means I have to 
store the minor separatly to call device_destroy())

Thanks
Malte

FYI: I am running a 3.19.0 Kernel
