Subject: [PATCH v3 3/3] clocksource/drivers/exynos_mct: increase the size of name array
Date: Mon, 21 Feb 2022 23:15:47 +0530	[thread overview]
Message-ID: <20220221174547.26176-3-alim.akhtar@samsung.com> (raw)
In-Reply-To: <20220221174547.26176-1-alim.akhtar@samsung.com>

Variable _name_ hold mct_tick number per cpu and it is currently
limited to 10. Which restrict the scalability of the MCT driver for
the SoC which has more local timers interrupts (>= 12).
Increase the length of it to make mct_tick printed correctly for
each local timer interrupts per CPU.
