Subject: arm64: include linux/types.h in asm/spinlock_types.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=772d68355e2f65f71e0402e39aabfdea56f55083;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm64: include linux/types.h in asm/spinlock_types.h

Our ticket-based spinlock structures rely on a definition of u16, so
include linux/types.h explicitly to ensure the thing compiles.

Found by a module build failure in -next:

  arch/arm64/include/asm/spinlock_types.h:27:2: error: unknown type name 'u16'
  arch/arm64/include/asm/spinlock_types.h:28:2: error: unknown type name 'u16'
  arch/arm64/include/asm/spinlock_types.h:33:13: error: expected declaration specifiers or '...' before numeric constant
  include/linux/spinlock_types.h:21:2: error: unknown type name 'arch_spinlock_t'
  arch/arm64/include/asm/spinlock.h:34:35: error: unknown type name 'arch_spinlock_t'
  arch/arm64/include/asm/spinlock.h:65:37: error: unknown type name 'arch_spinlock_t'
