Subject: ste_dma40: Delete an unnecessary variable initialisation in d40_probe()
X-Git-Tag: v4.5-rc1~51^2~11^2

ste_dma40: Delete an unnecessary variable initialisation in d40_probe()

The variable "res" will eventually be set to a resource pointer from
a call of the d40_hw_detect_init(() function.
Thus let us omit the explicit initialisation at the beginning.
