Subject: irqchip/renesas-rzv2h: Use local device pointer in ICU probe
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bbe78cb1399b4ba6b6d14943fb9dadefe9c17b5b;p=thirdparty%2Flinux.git

irqchip/renesas-rzv2h: Use local device pointer in ICU probe

Use a local struct device pointer in rzv2h_icu_probe_common() to avoid
repeated dereferencing of pdev->dev.
