Subject: toshiba_acpi: Remove TOS_FAILURE check from some functions
X-Git-Tag: v5.15~15462^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8baec45da1181572c0f8dc40c421c3f7ebecb0ab;p=platform%2Fkernel%2Flinux-starfive.git

toshiba_acpi: Remove TOS_FAILURE check from some functions

This patch removes the check for TOS_FAILURE whenever we are using
the tci_raw function call, as that code is only returned by the
{hci, sci}_{read, write} functions and never by the tci_raw, and
thus making that check irrelevant.
