Subject: video: fbdev: pxafb: Use correct return value for pxafb_probe()
Git-commit: f35b1d6c21b414e960ae3a9f1164fc691e1c3ab2
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
