It was reported on Turris forum [1] that HALNy HL-GSFP module does not work as it should with kernel 5.15. Russell King prepared this patch series, which fixes broken SFP module to work. Compile and run tested with Turris Omnia. [1] https://forum.turris.cz/t/hbl-turrisos-6-0-alpha2-halny-hl-gsfp-sfp-gpon-stick-problems/17547 Signed-off-by: Josef Schlehofer <pepe.schlehofer@gmail.com>
