Subject: [PATCH][next] drm/i915/psr: fix copy-paste error with setting of tp2_wakeup_time_us

From: Colin Ian King <[email protected]>

Currently for the psr_table->tp2_tp3_wakeup_time case 3 there appears
to be a copy-paste error from the previous switch statement where
dev_priv->vbt.psr.tp1_wakeup_time_us is being assigned and I believe
it should be dev_priv->vbt.psr.tp2_tp3_wakeup_time_us that should be
assigned instead.

Detected by CoverityScan, CID#1470105 ("Copy-paste error")

Fixes: 77312ae8f071 ("drm/i915/psr: vbt change for psr")
