Subject[PATCH AUTOSEL 4.19 064/252] drm/gma500: remove set but not used variable 'error'
Date
From: zhengbin <zhengbin13@huawei.com>

[ Upstream commit a5eb29a9d2fc03d07af7d02f6c2e7ae1e6d985f9 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/gma500/psb_irq.c: In function psb_sgx_interrupt:
drivers/gpu/drm/gma500/psb_irq.c:210:6: warning: variable error set but not used [-Wunused-but-set-variable]

It is introduced by commit 64a4aff283ac ("drm/gma500:
Add support for SGX interrupts"), but never used, so remove it.
