Subject: spi: add of_device_uevent_modalias support
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3ce6c9e2617e;p=linux.git

spi: add of_device_uevent_modalias support

Add OF support as already done for ACPI to take driver
MODULE_DEVICE_TABLE(of, ..) into account.

For example with this change a spi nor device MODALIAS changes from:

MODALIAS=spi:spi-nor

to

MODALIAS=of:Nspi-flashT(null)Cjedec,spi-nor
