Please apply the updated version at [1], the current version is
obviously not correct, as clang points out in next-20230714:

drivers/mtd/nand/onenand/onenand_omap2.c:470:2: warning: variable 'c' is uninitialized when used here [-Wuninitialized]
470 | c->onenand.base = devm_platform_get_and_ioremap_resource(pdev, 0, &res);
| ^
drivers/mtd/nand/onenand/onenand_omap2.c:465:25: note: initialize the variable 'c' to silence this warning
465 | struct omap2_onenand *c;
| ^
| = NULL
1 warning generated.

KernelCI also reported this at [2]. I apologize if this has already been
reported or fixed locally, I did not see your branch updated.
