Subject: [PATCH] ArmPlatformPkg/NorFlashDxe: eliminate void pointer arithmetic
Date: Mon, 24 Oct 2016 14:01:15 +0100	[thread overview]
Message-ID: <1477314075-18874-1-git-send-email-ard.biesheuvel@linaro.org> (raw)

While most compilers happily allow arithmetic on void pointer,
the RVCT compiler does not, and throws the following warning for
NorFlashDxe:

  ArmPlatformPkg/Drivers/NorFlashDxe/NorFlashDxe.c(894,48) :
  error  #1254-D: arithmetic on pointer to void or function type

Since the expression in question involves a cast from UINTN to VOID*,
simply add some parentheses to eliminate this warning.
