[PATCH 6.19 620/844] clk: tegra: tegra124-emc: Fix potential memory leak in tegra124_clk_register_emc()

[Sasha Levin]

From: Haoxiang Li <lihaoxiang@xxxxxxxxxxxxxxxx>

[ Upstream commit fce0d0bd9c20fefd180ea9e8362d619182f97a1d ]

If clk_register() fails, call kfree to release "tegra".

Fixes: 2db04f16b589 ("clk: tegra: Add EMC clock driver")
