Subject: ARM: 7905/1: etm: Remove unnecessary amba_set_drvdata()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=de77d1e5b412b31aa2f382bc6fe048d84e28d48e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: 7905/1: etm: Remove unnecessary amba_set_drvdata()

Driver core clears the driver data to NULL after device_release
or on probe failure, so just remove it from here.

Driver core change:
"device-core: Ensure drvdata = NULL when no driver is bound"
