Subject: [PATCH] bus: mhi: host: remove unused-but-set parameter

From: Arnd Bergmann <arnd@...db.de>

Clang warns about a parameter that is decremented but never evaluated heere:

bus/mhi/host/main.c:803:13: error: parameter 'event_quota' set but not used [-Werror,-Wunused-but-set-parameter]
                             u32 event_quota)

Remove the access to the variable to avoid that warning.
