Change the 'ret' variable in of_platform_mb862xx_probe() from unsigned long to int, as it needs to store either negative error codes or zero. Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but can be confusing. Additionally, assigning negative error codes to unsigned type may trigger a GCC warning when the -Wsign-conversion flag is enabled. No effect on runtime.
