Merge branch 'net-phy-realtek-add-support-for-phy-leds'
Michael Klein says: ==================== net: phy: realtek: Add support for PHY LEDs Changes in V7: - Remove some unused macros (patch 1) - Add more register defines for RTL8211F (patch 3) - Revise macro definition order once more (patch 4) Changes in V6: - fix macro definition order (patch 1) - introduce two more register defines (patch 2) Changes in V5: - Split cleanup patch and improve code formatting Changes in V4: - Change (!ret) to (ret == 0) - Replace set_bit() by __set_bit() Changes in V3: - move definition of rtl8211e_read_ext_page() to patch 2 - Wrap overlong lines Changes in V2: - Designate to net-next - Add ExtPage access cleanup patch as suggested by Andrew Lunn ==================== Link: https://patch.msgid.link/20250504172916.243185-1-michael@fossekall.de Signed-off-by: Paolo Abeni <pabeni@redhat.com>
