But this patch also needs to have its HID parts split out from the rest and the HID patches need to be merged separately. Since the merge-window is getting close I would like to propose the following: 1. Send a v7 addressing review remarks consisting of only patches 1-12, assuming all review remarks are fixed in v7 I can merge that then. 2. Send a 3 patch HID patch series separately: [PATCH 1/3] HID: amd_sfh: rename float_to_int() to amd_sfh_float_to_int() [PATCH 2/3] HID: amd_sfh: adding the HID hpd bits + amd_get_sfh_info() function [PATCH 3/3] HID: amd_sfh: adding the HID als bits 3. Once v7 of patches 1-12 + hopefully the 3 patch HID series have landed in 6.8-rc1 then I would be willing to take a patch using amd_get_sfh_info() to implement hpd + als support in the spc code as a fix for 6.8-rc# .
