Subject: mtd: rawnand: gpmi: remove unused parameters
X-Git-Tag: v5.15~5949^2~5^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ad8b4f1454ad2c7509bc8bf8930bead59619d117;p=platform%2Fkernel%2Flinux-starfive.git

mtd: rawnand: gpmi: remove unused parameters

gpmi_ecc_read_page_data uses the page parameter only for a debug printf,
so we can drop the parameter and the debug printf. Moving the oob
delivery from gpmi_ecc_read_page_data to gpmi_ecc_read_page makes the
oob_required parameter unnecessary aswell.
