Subject: mtd: nand: gpmi: fixup return type of wait_for_completion_timeout
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=706d5b289924678de9d8af67bcb00e28c1a5000c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: nand: gpmi: fixup return type of wait_for_completion_timeout

return type of wait_for_completion_timeout is unsigned long not int. The
return variable is renamed to reflect its use and the type adjusted to
unsigned long.
