Subject: dpll: zl3073x: Fix double free in zl3073x_devlink_flash_update()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=347afa39042728267550fa7a5ab5e9af52671add;p=users%2Fhch%2Fmisc.git

dpll: zl3073x: Fix double free in zl3073x_devlink_flash_update()

The zl3073x_devlink_flash_prepare() function calls zl3073x_fw_free() and
the caller, zl3073x_devlink_flash_update(), also calls that same free
function so it leads to a double free.  Delete the extra free.
