[PATCH v2 0/6] clk: mediatek: fix memory leak on module removal

[Akari Tsuyukusa]

Some MediaTek clock drivers do not call platform_set_drvdata()
during probe,
but their remove callback calls platform_get_drvdata().
This results in platform_get_drvdata() returning NULL,
which leads to calling kfree(NULL) in mtk_free_clk_data(NULL).
This leaves clk_data unreleased, causing a memory leak.

Fix this by calling platform_set_drvdata() during probe.

Changes in v2:
- Add a newline between platform_set_drvdata() and return
  (suggested by Brian Masney)
- Split the patch per SoC, (also suggested by Brian Masney)
- Add "Cc: stable at vger.kernel.org"
