Subject: thunderbolt: Fix double free of drom buffer

From: Andreas Noever <[email protected]>

commit 2ffa9a5d76a75abbc1f95c17959fced666095bdd upstream.

If tb_drom_read() fails, sw->drom is freed but not set to NULL. sw->drom is then freed again in the error path of tb_switch_alloc().

The bug can be triggered by unplugging a thunderbolt device shortly after it is detected by the thunderbolt driver.

Clear sw->drom if tb_drom_read() fails.
