Subject: [PATCH 2/5] ice: remove unnecessary PF_SB_REM_DEV_CTL write for E82X
Date: Thu, 30 Apr 2026 14:25:59 +0200	[thread overview]
Message-ID: <20260430122602.126722-3-aleksandr.loktionov@intel.com> (raw)
In-Reply-To: <20260430122602.126722-1-aleksandr.loktionov@intel.com>

From: Karol Kolacinski <karol.kolacinski@intel.com>

Remove the PF_SB_REM_DEV_CTL register write from ice_ptp_init_phc_e82x().
PHY access is enabled by default on E82X devices and the driver does not
need to configure switch device access. The register write was a
remnant of an earlier SWITCH_MODE workaround for a FIFO issue and is
no longer needed.

Also update the kernel-doc comment to refer to the E82X family rather than
E822.
