[PATCH 5.13 024/113] drm/i915/dp: Drop redundant debug print

[Greg Kroah-Hartman]

From: Swati Sharma <swati2.sharma@xxxxxxxxx>

commit 71de496cc489b6bae2f51f89da7f28849bf2836e upstream.

drm_dp_dpcd_read/write already has debug error message.
Drop redundant error messages which gives false
status even if correct value is read in drm_dp_dpcd_read().

v2: -Added fixes tag (Ankit)
v3: -Fixed build error (CI)

Fixes: 9488a030ac91 ("drm/i915: Add support for enabling link status and recovery")
