soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc

2022-06-09T08:25:32Z

[ Upstream commit ba56291e297d28aa6eb82c5c1964fae2d7594746 ] The allocation funciton devm_kcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly return -ENOMEM just like the usage of devm_kcalloc in previous code.

soc: ti: wkup_m3_ipc: Fix IRQ check in wkup_m3_ipc_probe

2022-04-08T11:57:46Z

[ Upstream commit c3d66a164c726cc3b072232d3b6d87575d194084 ] platform_get_irq() returns negative error number instead 0 on failure. And the doc of platform_get_irq() provides a usage example: int irq = platform_get_irq(pdev, 0); if (irq < 0) return irq; Fix the check of return value to catch errors correctly.

find_first{,_zero}_bit is a more effective analogue of 'next' version if start == 0. This patch replaces 'next' with 'first' where things look trivial. Signed-off-by: Yury Norov Tested-by: Wolfram Sang

The function has no users and is pointless now that the core frees the MSI descriptors, which means potential users can just use msi_domain_free_irqs().
