[igt-dev] [PATCH v2 i-g-t 23/23] tests/kms_dp_dsc: Read the debugfs only once

[venkata.sai.patnana at intel.com]

From: Patnana Venkata Sai <venkata.sai.patnana at intel.com>

Instead of doing a debugfs_simple_read and then
a debugfs_read(), lets read the debugfs node just once.
We anyway get the suitable return from the following
strstr operation

v2: using igt_debugfs_simple_read instead igt_debugfs_read (karthik)
v3: using igt_debugfs_read to instead igt_debugfs_simple_read
