Subject: Staging: ipack/bridges/tpci200: removed check of tpci200->slots[dev->slot].dev
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=65260291c13d148a7b7f86f3a99af14c43599fa9;p=openwrt%2Fstaging%2Fblogic.git

Staging: ipack/bridges/tpci200: removed check of tpci200->slots[dev->slot].dev

When ipack_device_register() is called, the variable
tpci200->slots[dev->slot].dev has not assigned a value and it gives an error
when the mezzanine driver is reading a register from the board for the match()
function, as all the I/O functions call check_slot().
