[PATCH 8/9] drm/nouveau/pci: Move an expression into a function call parameter in nvkm_pcie_set_link()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Date: Sun, 16 Apr 2023 08:45:31 +0200

The variable “pbus” was read only once in the implementation of
the function “nvkm_pcie_set_link”.
Thus move the usage of an expression into a parameter for a function call.
