From: Ilan Peer Date: Wed, 4 Oct 2023 09:36:30 +0000 (+0300) Subject: wifi: iwlwifi: mvm: Don't always bind/link the P2P Device interface X-Git-Tag: v6.6.7~1486 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=64c277f6329818db3124c9759cb9acf0f6070a54;p=platform%2Fkernel%2Flinux-starfive.git wifi: iwlwifi: mvm: Don't always bind/link the P2P Device interface [ Upstream commit 84ef7cbe90e9e54c71c1da4e645ba34e1b33da77 ] It is not necessary to keep the P2P Device bound/linked to a PHY context when there is no active ROC. Modify the P2P Device flows so the binding/linking would be done only while ROC is active. With this change the switch_phy_ctxt() is no longer needed so remove it.
