From: Varadarajan Narayanan Date: Fri, 18 Aug 2017 07:29:51 +0000 (+0530) Subject: PCI: qcom: Use block IP version for operations X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=deff11f884f0056d3f3fde2f526aaab70309255f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git PCI: qcom: Use block IP version for operations Presently, when support for a new SoC is added, the driver ops structures and functions are versioned with plain 1, 2, 3 etc. Instead use the block IP version number.
