[edk2] [PATCH 10/19] ArmPlatformPkg: HdLcdArmVExpressLib: Remove status check EFI_TIMEOUT
Posted by evan.lloyd@arm.com 7 years, 3 months ago
From: Girish Pathak <girish.pathak@arm.com>

None of the ArmPlatformSys*  functions return EFI_TIMEOUT. Hence checking
this in the do {} while loop in LcdPlatformSetMode is wrong. Therefore
remove this comparision and as a result remove the do {} while loop.

Still, this is a 3-space indentation that should be a 2-space
indentation.
