[PATCH i-g-t] kms_cursor_crc: Move igt_pipe_crc_{new, free} to init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If a subtest fails, cleanup_crtc() never gets called.  Currently that
also causes igt_pipe_crc_free() to never be called, leading all
subsequent subtests to also fail with -EBUSY at igt_pipe_crc_new().
Move the calls to igt_pipe_crc_{new,free} into igt_main so that
we don't need to worry about closing and reopening the CRC
filedescriptor for each subtest.
