Subject: i2c: tegra: Use platform_get_irq()
X-Git-Tag: v5.10-rc1~67^2~22
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=20b9a6c3ef2cb41de1bde1a89cbbb2e4abe58467;p=thirdparty%2Flinux.git

i2c: tegra: Use platform_get_irq()

Use common helper for retrieval of the interrupt number in order to make
code cleaner. Note that platform_get_irq() prints error message by itself.
