Subject: [PATCH RESEND] soc/tegra: fuse: Use device-specific instance in suspend/resume
Date: Thu, 14 May 2026 11:05:18 +0530 [thread overview]
Message-ID: <20260514053518.2402597-1-kkartik@nvidia.com> (raw)
Avoid using the default fuse instance in suspend/resume callbacks, as it
always runs the suspend/resume callbacks for the default instance rather
than the device’s own.
Get the correct fuse instance by using `dev_get_drvdata()`.
