irqchip: Convert all platform MSI users to the new API

[ Upstream commit 14fd06c776b5289a43c91cdc64bac3bdbc7b397e ] Switch all the users of the platform MSI domain over to invoke the new interfaces which branch to the original platform MSI functions when the irqdomain associated to the caller device does not yet provide MSI parent functionality. No functional change.

This commit makes the invocation of

platform_msi_domain_free_irqs_all(hba->dev);

conditional on

if (host->esi_enabled)

The original code before 5df23ec861a0208ef524a27e44c694ca2decb7ea was:

platform_msi_domain_free_irqs(hba->dev);

@@ -1926,7 +1926,7 @@ static void ufs_qcom_remove(struct platform_device *pdev) pm_runtime_get_sync(&(pdev)->dev); ufshcd_remove(hba);

• platform_msi_domain_free_irqs(hba->dev);

• platform_device_msi_free_irqs_all(hba->dev);

}

which means the whole backport is not required and just commit 64506b3d23a3 needs to be adjusted for pre 5df23ec861:

- platform_msi_domain_free_irqs(hba->dev); + if (host->esi_enabled) + platform_msi_domain_free_irqs(hba->dev);

Thanks,
