#     gpu: host1x: fix uninitialized variable use
#     
#     The error handling for platform_get_irq() failing no longer works after
#     a recent change, clang now points this out with a warning:
#     
#       drivers/gpu/host1x/dev.c:520:6: error: variable 'syncpt_irq' is uninitialized when used here [-Werror,-Wuninitialized]
#               if (syncpt_irq < 0)
#                   ^~~~~~~~~~
#     
#     Fix this by removing the variable and checking the correct error status.
#     
#     Fixes: 625d4ffb438c ("gpu: host1x: Rewrite syncpoint interrupt handling")
