Subject: i3c: master: svc: fix check wrong status register in irq handler
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=225d5ef048c4ed01a475c95d94833bd7dd61072d;p=linux.git

i3c: master: svc: fix check wrong status register in irq handler

svc_i3c_master_irq_handler() wrongly checks register SVC_I3C_MINTMASKED. It
should be SVC_I3C_MSTATUS.

Fixes: dd3c52846d59 ("i3c: master: svc: Add Silvaco I3C master driver")
