+Subject: drm/exynos: fix accidental on-stack copy of exynos_drm_plane
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit 960b537e91725bcb17dd1b19e48950e62d134078 ]
+
+gcc rightfully complains about excessive stack usage in the fimd_win_set_pixfmt()
+function:
+
+drivers/gpu/drm/exynos/exynos_drm_fimd.c: In function 'fimd_win_set_pixfmt':
+drivers/gpu/drm/exynos/exynos_drm_fimd.c:750:1: error: the frame size of 1032 bytes is larger than 1024 byte
+drivers/gpu/drm/exynos/exynos5433_drm_decon.c: In function 'decon_win_set_pixfmt':
+drivers/gpu/drm/exynos/exynos5433_drm_decon.c:381:1: error: the frame size of 1032 bytes is larger than 1024 bytes
+
+There is really no reason to copy the large exynos_drm_plane
+structure to the stack before using one of its members, so just
+use a pointer instead.

+Subject: gpio: eic-sprd: Clear interrupt after set the interrupt type
+
+From: Wenhua Lin <Wenhua.Lin@unisoc.com>
+
+[ Upstream commit 84aef4ed59705585d629e81d633a83b7d416f5fb ]
+
+The raw interrupt status of eic maybe set before the interrupt is enabled,
+since the eic interrupt has a latch function, which would trigger the
+interrupt event once enabled it from user side. To solve this problem,
+interrupts generated before setting the interrupt trigger type are ignored.

+Subject: spi: bcm-qspi: fix SFDP BFPT read by usig mspi read
+
+From: Kamal Dasu <kamal.dasu@broadcom.com>
+
+[ Upstream commit 574bf7bbe83794a902679846770f75a9b7f28176 ]
+
+SFDP read shall use the mspi reads when using the bcm_qspi_exec_mem_op()
+call. This fixes SFDP parameter page read failures seen with parts that
+now use SFDP protocol to read the basic flash parameter table.
