Subject: [PATCH AUTOSEL 4.19 140/191] ARM: tegra: apalis_t30: fix mcp2515 can controller interrupt polarity

From: Marcel Ziswiler <marcel.ziswiler@...adex.com>

[ Upstream commit b38f6aa4b60a1fcc41f5c469981f8f62d6070ee3 ]

Fix the MCP2515 SPI CAN controller interrupt polarity which according
to its datasheet defaults to low-active aka falling edge.
