From: Alex Williamson Date: Wed, 5 Jan 2011 17:26:41 +0000 (-0700) Subject: PCI: sysfs: Update ROM to include default owner write access X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ff29530e651a3449aea6b0ef4c7048db9e22ef27;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git PCI: sysfs: Update ROM to include default owner write access The PCI sysfs ROM interface requires an enabling write to access the ROM image, but the default file mode is 0400. The original proposed patch adding sysfs ROM support was a true read-only interface, with the enabling bit coming in as a feature request. I suspect it was simply an oversight that the file mode didn't get updated to match the API.
