Subject: lib/igt_debugfs: Don't fail if debugfs is already mounted
X-Git-Tag: intel-gpu-tools-1.8~276
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aba3582bb402b5cb5e48d81c5e32231fa42634d7;p=platform%2Fupstream%2Fintel-gpu-tools.git

lib/igt_debugfs: Don't fail if debugfs is already mounted

Remove the igt_assert() from the debugfs mount. It will fail if debugfs
is already mounted. With the assert in place it's very annying to use
igt without i915 loaded (eg. to dump BIOS configured registers).
