mtd: rawnand: mxs_nand: Ensure err is set for error path

2025-08-03T08:22:04Z

In mxs_nand_init_ctrl there are a couple of error paths that do not set err which could lead to the errors being silently ignored despite the function not completing. Rather than just using if to detect these errors use err to collect the error return value from the called functions. This issue was found by Smatch.

mtd: rawnand: denali: Remove always true test

2025-08-03T08:22:04Z

In denali_wait_for_irq the code will either return from inside the while loop or exit with time_left being 0. The following test for time_left being 0 is guranteed to be true so remove the test and the following unreachable code. This issue was found by Smatch.

mtd: rawnand: cortina_nand: Fix -ENOMEM detection

2025-08-03T08:22:04Z

In init_nand_dma there was code to detect failure to allocate memory but it had two problems. Firstly the 2nd clause when info->tx_desc was NULL attempted to free info->tx_desc when it should be freeing info->rx_desc. Secondly there was no detection of both allocations failing, arguably the more likely scenario. Refactor the code to simplify it and just fail as soon as either allocation fails.
