Subject: Revert "PCI: get larger bridge ranges when space is available"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=55a1098476619d5d8f4cdae7240ea759274dead7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Revert "PCI: get larger bridge ranges when space is available"

This reverts commit 308cf8e13f42f476dfd6552aeff58fdc0788e566.  This
patch had trouble with transparent bridges, among other things.  A more
readable and correct version should land in 2.6.33.
